Core Gameplay Mechanics and Flow
The base gameplay revolves around matching symbols across the reels. Wild icons substitute any regular symbol in winning combinations, while scatters initiate free spins or bonus features.

Wild Symbols, Scatter Symbols, and Special Icons

Bonus Features and Bonus Rounds
Apart from the Thunderstorm feature, there are two other main bonus features:
- Free Spins : Triggered by three golden rings landing in combination. These award an additional set of 10-20 spins with doubled or tripled payouts, as well as higher multipliers (up to x5).
- Pick-a-Pile Bonus : Initiated when two or more high-value symbols land on the same position on the fifth reel.
