The Scatter symbol (depicted as two rams) unlocks Thunderstruck's most powerful bonus feature. Landing 3 or more Scatters anywhere on the reels triggers both instant cash rewards and the coveted Free Spins round.

This bonus mechanic delivers consistent excitement and represents the slot's primary path to substantial payouts, making each scatter symbol appearance a thrilling moment.
