Bonus functions and unique mechanics
- The main feature of the slot is its unique mechanics. Symbols do not simply fall, but move along the spiral from the outer edge to the center. With each win, the 'Avalanche' feature activates: winning symbols disappear, and new ones take their place, potentially creating a chain of wins.
- If a spin does not bring a win, one of four random bonus features activates:
- Starfall Wilds: adds a wild symbol (Wild) to the field, which can substitute for any other to create a winning combination.
- Dragon Destroy: the dragon destroys one or several low-paying symbols, freeing up space for new ones.
- Irish Luck: Finn adds random symbols to the field to guarantee wins.
- Magic Transform: all symbols of the same type transform into a more valuable symbol.
- The key to the main bonus — Golden Key. When it reaches the center of the spiral, one of four types of non-paying spins is triggered, each with its unique modifier:
- Star Bar: each spin starts with one or more Wilds.
- Lava Lair: after each win, all low-paying symbols are removed.
- Golden Pot: before each spin, all symbols of the same type transform into a more valuable one.
- Dynamite Mine: before each spin, explosive Wilds are added to the field.
