Game Rules

Wild Symbols

Wild symbols substitute for adjacent regular symbols horizontally or vertically, but do not substitute for Scatter or Draugr symbols. The Hero symbol acts as a Wild only when it is on the game board and not moving.

Hero Hunt Feature

The “Hero Hunt” feature activates when no winning clusters remain on the game grid. The Hero symbol hunts down the Draugr symbols present on the grid and defeats them, destroying the symbols it passes over. The Hero symbol then remains in place until its next move or the end of the game round. Defeated Draugr may leave behind Loot and award multipliers.

Abilities

Increased chance of loot and a +1–2 multiplier for each Draugr.
High chance of loot and a +2–3 multiplier for each Draugr.
Adds 1–2 Draugr symbols.
Adds 3–5 Draugr symbols.
Symbols on the hero’s path are replaced by Mystery symbols.
Mystery symbols can transform into Wild symbols.

Troll Feature

A special Troll symbol may appear before a series of spins concludes. As it moves, the Troll destroys symbols within a 3×3 area and counts as 9 Draugr; defeating it can yield loot and multipliers.

Global Multiplier

The global multiplier applies to all cluster wins and Loot Wins. It increases the win amount after the initial calculation and resets at the start of each new game round or series of free spins.

Bonus Game

The bonus game can trigger upon the completion of a spin sequence. Each Scatter symbol offers a chance to activate the bonus game; there is no fixed requirement for the number of Scatter symbols needed. Upon activation, the player is awarded 5 free spins, along with 1–3 random abilities or upgrades. During the bonus game, for every 20 Draugr defeated, the player receives an additional 2 free spins and 1–3 random abilities or upgrades at the end of the free spin sequence. For the purpose of this count, a Troll is equivalent to 9 defeated Draugr. If all abilities have already reached their maximum level, only 2 additional free spins are awarded.

Cluster Pay

Payouts under the “Cluster Pays” system are awarded when 5 or more identical symbols (excluding Scatter and Draugr symbols) connect horizontally or vertically. Winning symbols are removed, and new ones drop into their place via the “Avalanche” mechanic. If a Hero symbol is present on the grid, symbols shift toward it and may appear from various directions. The sequence continues as long as new winning combinations are formed or additional features are triggered.
