Thunderstruck

Thunderstruck is a Norse mythology-themed slot game developed by Games Global (formerly Microgaming) and released in 2004. The game features a 5×3 grid layout with 9 paylines, set against a backdrop of dark, stormy clouds. The symbols on the reels include iconic Norse elements such as Thor's hammer (Mjolnir), a castle (possibly Asgard), a horn, and lightning bolts. These are complemented by high-value playing card symbols.

The game's Wild symbol is represented by Thor himself. This Wild can substitute for all other symbols except the Scatter to form winning combinations. Additionally, any win that includes a Wild symbol is doubled, adding an extra layer of excitement to the base game.

The Scatter symbol in Thunderstruck is depicted as two rams. Landing three or more Scatters anywhere on the reels triggers the Free Spins feature, awarding 15 free spins. During this bonus round, all wins are tripled, significantly increasing the potential for substantial payouts. The Free Spins can be retriggered by landing additional Scatters during the feature, with no limit on how many times this can occur.

Thunderstruck also includes a Gamble feature, allowing players to potentially double or quadruple their wins by correctly guessing the color or suit of a face-down card. However, an incorrect guess results in the loss of the original win.

One of the most notable aspects of Thunderstruck is its enduring popularity despite its relatively simple gameplay and dated graphics. The game's combination of a popular theme, straightforward mechanics, and potentially lucrative Free Spins feature has helped it remain a favorite among players for nearly two decades.
