Powerful Bonus Features to Boost Wins
Thunder Shields Slot is brimming with engaging features designed to maximize winning potential and excitement:
- Wild Symbol & Colossal Respins
Thor’s hammer serves as the Wild, substituting for standard symbols and triggering the Colossal Respins feature. Upon triggering, giant symbols appear on reels 1 and 2. Additional Wilds during respins expand the giant symbols across up to four reels and can activate multipliers that increase with successive respins. - Mystery Spins
The Mystery Symbol appears fully or partially stacked, transforming into the same randomly chosen symbol when spins end. This can surprise players with sudden high-value line wins. - Hold & Win Respins & Cash Shields
Landing six or more Cash Shield symbols triggers the Hold & Win respins feature. Players receive three respins, which reset each time a new Cash Shield lands. This feature locks in the collected shields and boosts payout potential. - Special Shields & Bonuses
Within Hold & Win, special shields can appear:- x2 Multiplier doubles values
- Collector gathers all visible cash values
- Reel Boost adds extra reels (up to two additional reels)
- Cash Boost enhances current cash values
- Respin Boost grants extra respins.
- Thunderstorm Prizes
Secure three Thunderstorm (Storm) shield symbols during Hold & Win to unlock one of three instant prizes: Mini (10× bet), Major (100× bet), or Mega (1,000× bet). Multipliers from the special shields can further enhance these rewards.
Massive Winning Potential
With a base-game top win of about 250× your stake for five-of-a-kind Viking symbols, the true payouts shine in the bonus rounds. The Hold & Win feature offers a staggering maximum win potential of up to 4,035× your bet, combining Shield collections, multipliers, and jackpots for epic payouts.
