Thunderstruck II Slot Review

In 2004, the first version of Thunderstruck appeared and became one of the most popular slot machines ever. Microgaming decided to step it up a notch for this reason and created a sequel with Thunderstruck II, which far outshines its predecessor. With beautiful and atmospheric graphics, a catchy soundtrack, and convincing animations, Thunderstruck II is a winner, not least because of its 243 ways you can win.

Thunderstruck II consists of 5 reels and offers 243 ways to win. In this game, you need to spin the reels as usual, but there are a significantly larger number of ways to win. Even if you don’t win, the game still provides plenty of entertainment to keep you engaged.


The best thing about this game is the incredible abundance of special features, such as the wild card, which substitutes for other symbols and doubles at the same time. Additionally, there is the Wildstorm feature, which randomly turns 5 whales into wild symbols and can generate really high wins. There is no end here, because there is also the Bonus Hammer, which means that when 3, 4 or 5 Bonus Hammers appear on the reels, you enter the Great Hall of Spins, where there are many more winning opportunities. The first 5 times you enter the Great Hall of Spins, you get the Valkyrie Bonus, which gives you 10 free spins as well as quintupling your winnings. After the 5th visit, you get the Loki bonus, 15 free spins and the Wild Magic feature, which randomly turns symbols into more Wilds. Before going to Thor, you still have to overcome Odin, 20 free spins and the Wild Raven feature, which turns symbols into 2x to 3x multipliers. Finally, you meet Thor himself after 15 bonus rounds with 25 free spins and the Rolling Reels feature, which quintuples the winnings.

Conclusion of our test

In summary, Thunderstruck II is a highly impressive slot game that provides continuous entertainment. The theme is well-developed and executed flawlessly. Additionally, the game features multiple levels that players must progress through before encountering Thor, which adds to the excitement. Furthermore, the potential for massive wins makes this slot one of the best choices available.
