It remains a firm favourite with players who like epic sets of reels.

Game Info

Themed with Norse mythology, the Thunderstruck II slot gets down to business with a base-game of five reels, and 243 Ways to Win across them. Augmenting the standard symbols that combine for wins, the game logo appears as this slot’s Wild with its traditional power to substitute for all symbols except Thor’s Bonus Hammer symbol. Thor’s Hammer is reserved for special duties, as we’ll explain shortly. One unexpected feature that has built this slot’s legend is its Wildstorm bonus – this is randomly triggered, and gifts a free spin with between one and five reels turning fully Wild for this ride. It’s a very powerful way to win big, particularly if your luck sees all reels get the Wild treatment!

The star attraction for Thunderstruck II players is an invitation into its Great Hall of Spins feature. This is triggered when three or more of the Hammer Bonus symbol are in view on the base-game, and comprises four levels of Free Spins bonus games. Each level is themed with one of four Norse gods – Valkyrie, Loki, Odin and Thor – and progressively increases the number of free spins you win and upgrades the special Wild and Reel features that those are blessed with.

Which level you get to play depends on how many times you’ve triggered the feature, and this slot has a memory function to track that building up a personal playing history that let’s you explore all four in time! Adding to the lure of this feature, once you’ve experienced all four levels, your achievement earns you the right to freely pick which level you wish to play on all subsequent visits to the Great Hall of Spins. Very cool.


Thunderstruck II’s popularity is well deserved. If you love epic slots which make great play of free spins as their bonus feature, then this should be a game you’ll love to strike up a long term relationship with.
