What is Bjorn?

Bjorn is set in a dark Norse fantasy world where the axe-wielding hero hunts undead draugr. Runestones, trees, rocks and tree stumps fill the grid, while Bjorn, enemies and a Troll can move through the play area.

The base game revolves around cluster wins and avalanches. Once no new winning clusters are formed, the Hero Hunt can begin. Bjorn then moves towards the draugr on the grid, destroys symbols along his path and can collect loot and additional multipliers.

Symbols

The highest-paying regular symbols are three different runestones. The remaining paying symbols are a tree stump, bush, rock and pine tree. Larger clusters of matching symbols award higher payouts.

Bjorn also includes several special symbols. The Wild helps create regular cluster wins, while Bjorn's hero symbol can also act as a Wild when he is stationary. Draugr are the targets during the Hero Hunt, while the Troll can affect a larger part of the grid.

Scatters, loot, Mystery symbols and ability upgrades also play a role during the different stages of a round.

Wild

Wild symbols substitute for horizontally and vertically adjacent regular symbols to help create cluster wins. They do not replace Scatters or draugr symbols.

Bjorn himself also acts as a Wild while standing still on the grid. During movement in the Hero Hunt, the hero symbol temporarily loses this function.

His position also affects the avalanches. When Bjorn is present on the grid, new symbols can fall towards his position from different directions.

Scatter

The bonus game is not triggered by a fixed number of Scatters. At the end of a spin sequence, each Scatter currently present has an individual chance to trigger the Free Spins.

When the bonus is activated, 5 Free Spins are awarded. Bjorn also starts the feature with 1 to 3 random abilities or upgrades.

Hero Hunt

The Hero Hunt begins once there are no new winning clusters left on the grid. Bjorn then moves towards the draugr and defeats them one by one.

All regular symbols along his route are destroyed. This creates new empty positions that can then be filled by another avalanche.

After the hunt, the hero symbol remains in its new position until Bjorn moves again or the round ends. Defeated draugr can leave behind loot and increase the global multiplier.

Abilities

Bjorn has three different abilities, each with 2 levels. These upgrades can affect the amount of loot, the multiplier, the number of enemies and the route Bjorn takes through the grid.

Strength of Thor

Strength of Thor increases the potential of defeated draugr. At level 1, the chance of loot is increased and each defeated draugr adds between 1× and 2× to the global multiplier.

At level 2, this potential increase rises to between 2× and 3× per defeated draugr.

Call of Hel

Call of Hel adds additional draugr to the grid at the start of every spin or Free Spin.

Level 1 places 1 to 2 additional draugr. At level 2, 3 to 5 extra draugr are added.

Odin's Insight

Odin's Insight turns the positions Bjorn crosses during the Hero Hunt into Mystery symbols.

At level 1, these positions transform into random paying symbols. At level 2, the Mystery symbols can also transform into Wilds.

The abilities remain active throughout the full round and can be upgraded further during the bonus game.

Troll feature and loot

A special Troll symbol can appear before a spin sequence ends. The Troll moves through the grid and destroys symbols within a 3×3 area.

When Bjorn defeats the Troll, it can award loot and multipliers. For bonus progression, a defeated Troll also counts as 9 defeated draugr.

Loot can be left behind by both draugr and the Troll. Collected loot is awarded once there are no avalanches or draugr symbols remaining.

Global multiplier

The global multiplier is applied after the base value of all cluster and loot wins has been calculated.

Defeated draugr and the Troll can increase this multiplier. The amount of multiplier a draugr can add is partly determined by the current level of Strength of Thor.

The global multiplier resets at the start of every regular spin and each individual Free Spin. Its build-up therefore takes place within a single complete spin sequence.

Free Spins

The bonus game starts with 5 Free Spins and 1 to 3 random abilities or upgrades. These upgrades remain active throughout the bonus and can be improved further when enough draugr are defeated.

After each sequence, the number of defeated enemies is checked. Every 20 defeated draugr award 2 additional Free Spins and 1 to 3 random abilities or upgrades. A defeated Troll counts as 9 draugr for this progress.

Once all three abilities have reached their maximum level, each further group of 20 defeated draugr awards only the 2 additional Free Spins.

The bonus can therefore develop as it progresses: Bjorn can encounter more draugr, build stronger multipliers and transform more positions through Odin's Insight.

Maximum win

The maximum total win in Bjorn is 5,000× the stake.

Once this limit is reached during a round, the current round ends and no further wins are awarded.

The combination of cluster wins, loot and the global multiplier determines how a round can build. In particular, defeating several draugr while Strength of Thor is active, together with defeating a Troll, can further increase the multiplier within the same spin sequence.

Why Bjorn stands out

Bjorn combines a traditional cluster mechanic with a hero who physically moves through the grid. The action starts with cluster wins and avalanches, after which the Hero Hunt can reopen the round by defeating draugr and removing symbols along Bjorn's route.

The three abilities give each round a different development. Strength of Thor affects loot and multipliers, Call of Hel adds extra draugr and Odin's Insight transforms Bjorn's path into Mystery symbols that can later also become Wilds.

During the Free Spins, these abilities can be upgraded further. This means the bonus can evolve from a simple start with only a few upgrades into a situation where all three abilities are active at their maximum level.

Is Bjorn worth playing?

Bjorn is designed for players who enjoy cluster wins, avalanches and bonus features that continue to develop during play. The combination of Hero Hunt, loot, global multipliers and upgradeable abilities gives each spin sequence a different structure.

This Thunderkick release combines an 8×8 grid, extendable Free Spins and a maximum win of 5,000× the stake.
