Collect Shield Symbols and Win Big

The wild symbols in the Thunder Shields online slot game come with a unique twist. Not only do they substitute regular symbols to help you achieve a winning payline, but they also activate Colossal Respins. This feature introduces large symbols covering reels 1 and 2, providing extra winning opportunities. If a wild symbol lands in these positions, the giant symbol will expand to cover up to four reels.

The Mystery Spin, triggered randomly, guarantees a minimum of three reels stacked with identical symbols, which are unveiled at the spin’s conclusion.

Watch out for the Cash Shields, as landing six or more of them will activate the Hold & Win Respins feature on the Thunder Shields slot machine. Initially, you receive three respins, and each new shield landing resets the respin count. Special shields bring multipliers, collectors, boosts, and other beneficial power-ups to enhance your final reward.

Additionally, while engaging in the Hold & Win Respins feature, three Thunderstorm prizes are up for grabs. Collect three storm shields to unlock either the Mini, Major, or Mega prize.
