Thunderstruck II by Microgaming Slot Theme

Thunderstruck II is based on Norse mythology, featuring the very well-known gods such as Thor, Loki and Odin.

The graphics aren’t the best you’ve ever seen, as Microgaming like to keep it simple. On the flipside, the background music and sound effects make up for any shortcomings as far as aesthetics go.

Main Features

The Great Hall of Spins is what Thunderstruck II is all about, as it opens the doors to great riches thanks to the unique set of bonus games on offer. The longer you play, the more features will open up, thus increasing your chances of greater winnings.


The Valkyrie bonus game is available from the 1st activation of the bonus feature. It rewards you with 10 free spins with an X5 multiplier. The free spins can be re-triggered.


The Loki bonus game is available from the 5th activation of the bonus feature. It rewards you with 15 free spins and the Wild Magic feature. The Wild Magic symbol can appear on the third reel and transform random symbols into Wilds.

In this bonus game, you can re-trigger up to 4 additional free spins during a single spin.


The Odin bonus game is opened after the 10th trigger of the bonus game. In it, you will be rewarded with 20 free spins and the Wild Raven feature. This feature visually presents ravens that can land on random symbols and transform them into multipliers, up to X6.


Lastly, we have the Thor bonus game, which nets you a whopping set of 25 free spins combined with the Rolling Reels feature. This feature hosts a multiplier starting at X2, which increases every time a consecutive win is hit – up to X5.

Thunderstruck II is also famed for its incredibly lucrative Wildstorm random-trigger feature. At any time during gameplay, Wildstorm can activate and fully turn up to 5 reels into Wilds. As you can already tell, the potential here is gigantic.

Thunderstruck II by Microgaming – Slot Review Summary

Thunderstruck II is greatly perceived in the majority of players worldwide, and deservedly so. The comprehensive bonus features may not be easy to get to, but once you’re there the potential is nigh limitless. Still, there’s something to said about the base game as well. It may not be able to make you a big winner by itself, but at least it can keep you in the game until you’ve started diving deep into the bonus round.

This is why we can easily recommend Thunderstruck II to low and high rollers alike.
