Thunderstruck II - the Norse Gods delivered a slot classic from the get-go
The original Thunderstruck slot was a very popular game by Microgaming and one of its early classics. Expectations were therefore very high for the sequel when it was announced.
However, it is fair to say that the Thunderstruck II slot has surpassed even those lofty expectations.
Based on the Norse God mythology, which is all the rage at the moment thanks to the appearance of many of the key characters in the Marvel Cinematic Universe, Thunderstruck II took the original game and built on it hugely, introducing a quest element to its Free Spins bonus rounds, a fantastic randomly triggered bonus and of course, a huge jackpot which could be worth more than 2,400,000 coins.
So what is it about this slot that made it an instant success at Microgaming casinos? Let's take a closer look and see if we can find out.

The five reels are presented at the centre of the screen with a stone, blue/grey livery. The controls of the slot are all at the foot of the reels and the animations that play when the reels spin are nicely done but hardly going to win any awards nowadays.
The musical accompaniment though is very nicely done, with a rather gentle and simple soundtrack in the main, which also features bursts of thunder and other sound effects which kick into play when some of the bonus features or wins are landed on the reels.
The presentation is also very nicely done when you trigger the random bonus in the base game and any of the four Free Spins bonus features, each of which has its own bonuses and effects.
What is on the reels?
In terms of the symbols on the reels there are a total of 14 different symbols, though two of these are the Wild and Scatter symbols, which we will look at in more detail below. Of the remaining 12 symbols, they are split evenly between higher and lower value symbols.
Lower value symbols are the six playing card values, from the nine through to the ace and these offer wins ranging from 5 coins up to 150 coins.
Higher value symbols are the Viking boat, the city of Asgard and four characters from Norse mythology including Valkyrie, Loki, Odin and Thor, who is the highest value of the standard symbols paying out 500 coins on a single line.
Thunderstruck II actually has two Wild features, the first of these being the Thunderstruck Wild symbol which can substitute for any of the standard symbols outlined above to help create additional wins on a spin. Furthermore, any win that a Wild forms part of will receive a 2x multiplier.
Land five of the Wild symbols across the reels and you will land the biggest value single line win in the game, which is 1,000 coins.
However, the randomly triggered base game the Wildstorm feature, is also based on Wild symbols. When this feature triggers, which can occur on any spin, for every reel that the Wildstorm lightning bolt strikes during the bonus, it will turn that entire reel Wild. You could possibly turn all five reels Wild in this feature, which can lead to the biggest possible win in the base game.
Free Spins features
Without doubt one of the most exciting aspects of the Thunderstruck II slot is its Free Spins bonus round aptly named the Great Hall of Spins. That is because this is accessed when you land three or more the Mjolnir Hammer Scatter symbols across the reels on any spin which then triggers the Great Hall of Spins feature.
Once you trigger the bonus, you then enter the Great Hall of Spins and you have four different Free Spins games, each with their own bonuses, to play through. You begin with the Valkyrie bonus and then as you progress through the game triggering the Great Hall of Spins bonus again and again, you will unlock the other Free Spins bonuses as you play.
The Free Spins bonus features are as follows:
- Valkyrie - 1st - 4th triggers of Free Spins - 10 Free Spins with a 5x multiplier and Free Spins can be re-triggered from within the bonus.
- Loki - 5th - 9th triggers of Free Spins - 15 Free Spins with Wild Magic Feature on Reel 3. This symbol can transform symbols into Wilds on other reels when landed. Furthermore, land two, three, four or five Scatters during the bonus and you will land 1, 2, 3 or 4 additional free spins respectively.
- Odin - 10th - 14th triggers of Free Spins - For this bonus you receive 20 Free Spins with the Wild Ravens feature which will see Odin's Ravens randomly turn symbols into 2x or 3x multipliers and if both Ravens land on the reel, this will see any winning spins receive a 6x multiplier.
- Thor - 15th trigger of free spins on wards - 25 Free Spins with Rolling Reels and a Multiplier Trail which increases the multiplier on Rolling Reels wins from 1x up to 5x the stated amount if Rolling Reels spins trigger consecutive wins.
Trigger the Great Hall of Spins bonuses enough times and eventually you will unlock all four of the Free Spins bonuses available and each time you subsequently land a bonus, you will get to choose which of the four bonus features you would like to play.
Best feature of the Thunderstruck II slot
With so many great features including the Wildstorm randomly triggered bonus, it is easy to see why the Thunderstruck II slot will become one of Microgaming's most popular games. However, the best feature is undoubtedly the Great Hall of Spins bonuses with the four different Free Spins games. Each player tends to have their favourite of the four games, personally, I like the Valkyrie and Thor bonus games more than the others, but you can win sizeable amounts playing any of the four features.
Thunderstruck II will in our has all the makings of a classic slot game that combines all its different elements into one of the most playable and enjoyable slots you can find anywhere online. It is easy to see therefore, why this slot instantly after its release became one of the most played games at Microgaming casinos.
