How the Game Plays

Thunder Shields takes players on a Viking voyage across a 5x4 grid set against the backdrop of a stormy sea and a longship. The high-value symbols feature four distinct Viking warriors, while lower values are represented by runic-style card royals. To secure a win, you must land at least three matching symbols across any of the 40 fixed paylines. The gameplay is fast-paced, supported by Mystery Symbol stacks that can transform into any standard symbol to create winning combinations.

Colossal Respins Explained

Landing a Thor's Hammer Wild symbol on the reels triggers the Colossal Respin feature. During this event, the first two reels merge to form giant symbols. If additional Wilds land during the respin, the colossal area can expand to cover reels 1 through 4. Continued Wild landings also activate a progressive multiplier, starting at 2x and increasing by 1 for every subsequent Wild, while also resetting the respin counter.

Hold & Win Feature Explained

The core attraction of this iSoftBet title is the Hold & Win bonus, triggered by landing six or more Cash Shield symbols. The grid transitions to a special 5x5 format where only shields and special modifiers can land. You begin with 3 respins, which reset whenever a new symbol lands. Modifiers include Multipliers (doubling all values), Collectors (gathering all cash to clear space), Reel Boosts (adding extra reels), and Cash Boosts. Within this mode, collecting three Storm Shields grants one of three Thunderstorm jackpots: the Mini (10x), Major (100x), or Mega (1,000x).
