- Free Spins Bonus: activates when 3 or more Scatters land. Consists of three consecutive stages:
- Stage 1: all low symbols (cards) are replaced with one of the trolls.
- Stage 2: Whirling Wilds appear — Wild symbols whirl after each win.
- Stage 3: adds a multiplier to the win up to x15, which applies to all wins.
The bonus does not reset, but each stage lasts until the player continues to win.
