Thunderstruck 2 Review - Editor’s Impressions

The Thunderstruck slot was launched in 2004 to much success, becoming a player favourite. Its sequel in the Thunderstruck 2 game revitalises the Norse mythology plot in the pioneer slot. This sequel slot has more gods and features with exciting rewards. Our initial impression of the game was solid and that was only enhanced after trying it out. 

This Thunderstruck 2 slot review will take you through the Nordic winter experience. You’ll also find out the best online casinos to play this game. 

Overview of Thunderstruck 2 Game

Games Global released this online casino slot in 2010 and then with its immense popularity remastered it in 2020. Thunderstruck 2 was developed on a standard five reels by three rows grid with 243 paylines. Unlike its predecessor, this slot is set in the ice-cold winter.  

On the grid, you’ll find symbols often found online slots with similar themes. Three more gods flank Thor in this game. With more gods come more rewards, as we’ve detailed below. In contrast with the game’s setting, the bonus rounds have a warm and inviting atmosphere. 

The colourful symbols in the game include the gods of Thor, the Thunderstruck II logo, a hammer, Odin, Loki, Valkyrie, a boat, rainbow castle and the typical card symbols of 9, 10, J, Q, K, and A. The game is simple to play with all of the betting control buttons at the bottom of the screen. There is an autospin feature, but it is not available for UK players. 

Thunderstruck 2 RTP, Payout and Volatility

The Thor symbol has the highest payout in this slot, followed closely by the other gods Odin, Loki, and Valkyrie. A boat and rainbow castle are the medium-paying symbols, and regular playing cards have the lowest payouts. 

The gods in this slot also have bonus round functions where they determine the number of Free Spins and their multipliers. 

The Thunderstruck 2 RTP is 96.65% and It’s also a high-volatility slot. This means you can land sizable payouts but less frequently at a Thunderstruck 2 online casino. You can bet a minimum of £0.30 and a maximum of £60 for a shot at this game’s £480,000 max win. As you can see with a very wide betting range the game is great for low stakes players and high rollers alike. 

Thunderstruck 2 Graphics and Gaming Experience 

This game is set in the ice age, like most Nordic-themed video slots. Games Global used high-quality graphics for the symbols in this game. As the game begins, you can hear soft, anticipatory music in the background. A bell and other sound effects will notify you of winnings and bonus features in this slot. In the settings section you can turn the sounds off if you wish. The engaging game has sounds and graphics that lead to a solid playing experience. 

Thunderstruck 2 Bonus Features 

If you’re coming from our online slot reviews, where we took you through the Thunderstruck slot machine game, you’ll be happy to discover more features in the sequel. 

The basic one is the Wilds symbol, which is the Thunderstruck II logo and it substitutes others to help complete winning lines. This slot also has a Wildstorm feature, appearing randomly in the base game rounds. When it occurs, five reels turn into Wilds for some possibly big wins. In the Windstorm feature Free Spins cannot be retriggered. 

Thunderstruck 2 Free Spins 

Scatters can fall anywhere on the grid to activate Free Spin rounds in this slot. Landing three or more Scatters triggers the Great Hall of Spins with four bonus features. 

On the first bonus trigger, you activate the Valkyrie bonus feature. It comes with 10 Free Spins, which can be retriggered. These Free Spins come with a 5x multiplier. 

On the fifth trigger, you can unlock the Loki feature. This gives you 15 Free Spins and the Wild Magic feature. When it lands on the third reel, it transforms 15 symbols into Wild Magic symbols. Landing two to five Scatters can retrigger the Free Spins during this feature. 

On the tenth trigger, you can land the Odin bonus feature. It comes with 20 Free Spins and the Wild Raven feature. The two ravens occasionally swoop in, bringing 2x and 3x multipliers. If they fly in together, they carry a 6x multiplier. 

The fifteenth trigger can activate the Thor bonus feature. It comes with 25 Free Spins and a Rolling Reels feature. This can increase the winnings as the matching symbols are removed and replaced with new ones for potential new wins. The multipliers also rise from 1x to 5x for consecutive wins. 

What Are The Pros and Cons of Playing Thunderstruck 2

A slot from Microgaming and based on the norse legend theme. It’s a sequel to the good old Thunderstruck 9 liner. This time Microgaming went with the more modern 243 ways type of slot design. The minimum bet comes it at 0.30 making it mostly suitable for most players although some might prefer lower, it is what it is.
The sounds are certainly suitable especially the hammer scatter sounds when they drop in and then you have the music during the features, each feature has it’s own music and since there are four different features there’s four different music soundtracks to enjoy while the feature plays.

As for the symbols appearing you get the main characters Valkyrie, Loki, Odin and Thor, all beautiful drawn. As well as the premium symbols you get some card symbols from 9 to Ace. There is also the wild symbol which is the Thunderstruck II logo and it doubles any wins it is part of.

Now onto the bonus feature - it is a matter of getting 3 or more scatters which happen to be the hammer symbols, this takes you to the next screen which is the Great Hall of Spins, where you get to see your feature progress and you start off with only being able to play the Valkyrie free spins which give you 10 free spins with a decent x5 multiplier. Free spins can be re-triggered by getting 3 or more scatters during these free spins. This feature can pay off good and my most recent Valkyrie feature paid 165x when five of a kind Odin landed with the help of two wilds.

The other features are the Loki where you get random wilds added, followed by Odin where ravens fly in, and Thor has rolling reels. If you think about it it is very similar to Immortal Romance, the way the features are unlocked and the feature types, just change of symbols.

There is one other thing about this slot which basically like in Immortal Romance and this time it is the Wildstorm. When during any spin you will get random reels turn wild and up to 5 reels can turn wild. Most of the time you will get 2 reels. And the most I have had is 3.

The RTP of the game is very decent at 96.65%.


One thing is that to get the choice of all 4 features you have to unlock them by getting at least 5 features and then you get access to the Loki feature but then to get access to Odin you need to play more and get more features and then once again more features to get access to Thor features.
If you play this at multiple casinos your progress is different at each casino and you won’t be able to play all features until you unlock them. Sometimes the progress can be reset if there is some casino issue going on!

Magnificent story design. Beautifully aligned symbols and kidnapping in the far past is a popular slot game on the planet. / And perhaps outside of it :) / The game often runs without a win and then suddenly encounters symbols that cause an explosion of joy. Or 3 or more of the hammers in the FS where the number of FS can be selected. I like this. Good work Microgaming.

I love the progression that's involved with Thunderstruck 2, when you hit the 3 to 5 hammers and get awarded a trip to the great hall, once you've played for awhile, a player gets to choose their reward between the 4 free spin features. I can't forget to mention that wilds double your win as well, makes for some huge wins here and there.


I really dislike the fourth bonus feature with Thor and the crumbling symbols after a win. I have played this game lots over the years and this feature included, but I almost never get rewarded with a winning spin that's higher than a base symbol, 10,J,Q,K,A . The other symbols almost never land, and when they do, it's not for any kind of win. For the fourth feature earned, showcasing the games main character, it sure does take away from the quality in this game.

The best part about Microgamings Thunderstruck 2 is when you progress further into the free spin bonuses and you get to choose what bonus you can play when you land the three or more hammers during gameplay. Being able too switch up the bonus round free spins adds another element of gameplay that in my personal opinion is a welcome feature.


The final bonus feature with 25 spins and Thor doesn't seem to land very much other then the basic symbols, the picture symbols land very few and almost never seem to amount to very much at all.

Thunderstruck II is a very popular game from the software called Microgaming. This is one of their older games and I think that all casinos who are powered by this software, have this game in their collection. I have tried this game several times but for some reason I never actually spent long sessions with it, as I mostly played it on free roll tournaments. And whenever I played it, I didn't manage to get nice wins so automatically I chose to avoid it.

The game is inspired by fantasy theme and there are magical creatures and letters used as symbols. Technically this game is a standard 5 reel and 243 ways to win slot with two bonus features. I have read many comments about this game and how it is very similar to Immortal Romance slot and I definitely agree with that as their bonus features are almost the same. I find it as a plus cause I love Immortal Romance.

A few days ago I decided to finally give this game a decent try at Slotjoint casino with a 50€ balance. I played with minimum bets only and my session lasted about two hours. I managed to get many free spins rounds and unlocked three chambers. The free spins are triggered by 3 or more bonus symbols and from all 4 free spins chambers, my favorite bonus is the Valkyrie feature as it gives 10 free spins with 5x multiplier and from all free spins I had, this feature gave me the biggest winnings of nearly 100x bet. But I also have to say that the Wild Storm feature is super exciting as it turns reels wild and this feature definitely has a huge winning potential. In my case I had this feature a few times in my session but there were no good winning combinations over 30x bet.

All in all I do enjoy this game and I managed to make profit out of small yet regular wins. The game definitely is exciting because if its' features but for me the only thing I am not that impressed with, is the design. There are many nice details but for some reason it's just not my cup of tea. However, I liked everything else and I will start to play it more often.

What? Writing a review on Thunderstruck 2, after all this years? Hmm, I have told you many times before that I was never a big fan of any Microgaming game, right? So there you go, after all these years, after many intermittent plays, only now I could muster up my keenness to finally write a review on this damn popular game. I may be Rip Van Winkle to you, but who cares! But now, I'm gonna rip, I'm gonna vent, I'm gonna wrinkle this Thunderstruck 2 game...if I can! Hahaha.

Most of you may already be familiar with this game, but please allow me to briefly say a few things nonetheless. Thunderstruck II is the Wild symbol, 5 of which pay 1000x the line bet, and doubles all wins with it too. Thor's Hammer is the Scatter symbol, 5 of which pay 200x the total bet, getting 3 or more of them award entry into The Great Hall of Spins, with 4 eventual choices of free spins features to choose from. Probably the best feature of all to aim for is the Wild Storm feature, randomly activated in the base game, turning up to 5 reels into full Wilds, as in Wild Desire of Immortal Romance. As if you didn't know hah? Hehehe. Thor is the highest paying normal symbol, at 500x the line bet for 5 of him, followed by 450x for Odin, 400x for Loki, 350x for Valkyrie, and 300x down to 100x the line bet for the other lower symbols.

The 4 Free Spins games are Valkyrie, offering 10 free spins with 5x multiplier, the only Free Spins game that can be retriggered, Loki is the second, offering 15 free spins with a Wild Magic feature that randomly transforms other symbols into Wilds, the third is Odin, offering 20 free spins with Wild Raven feature that turns random symbols into 2x and 3x multipliers, and the last, Thor, offering 25 free spins with Rolling Reels feature for multiple wins and with 2x up to 5x win multipliers. Which of these 4 are the best? Hmm, very hard to say, because each one can explode and pay out huge at any unexpected time, but I tend to prefer Loki and Odin a little bit more than Valkyrie or Thor. You may like any other one, I wouldn't be surprised at all.

Game play wise, Thunderstruck II is the predecessor to Immortal Romance, so is in fact the originator of any other similarly playing game. The original Thunderstruck game plays with only 9 paylines and is nothing like Thunderstruck II at all. Comparatively, I now prefer Thunderstruck II than Immortal Romance, simply because Immortal Romance has lied to me so many times before with its zero, almost zero, and ridiculously low payouts from its numerous Wild Desire features! About 4 out of 10 Wild Desire features would pay less than 1x the total bet and I've had 3 straight consecutive times with zero payouts! Just imagine that! No doubt I've also had a zero payout from the Wild Storm feature, but only once in awhile, and never yet consecutively.


Honestly speaking, I simply hate any 'special feature' that tend to pay out nothing! If it's a special feature, as in Wild Storm or Wild Desire features, then it MUST PAY something to justify its appearance! Can you ever expect any world-class celebrity to turn up at your special function without getting paid for his/her special appearance? Not on your life they won't! So Wild Storm and Wild Desire should do the same too! Paying nothing for something 'special' is a lot of bull-you-know-what to me!

Thunderstruck 2 was one of my first slots from Micogaming that I ever played, I loved it from the first time I played it and I still play it a lot after so many years, giving me the same excitement as it did, although it starts getting old. By the way when will they produce Thunderstruck 3?

Thunderstruck 2 is a 243 lines slot which has theme of Thor and the Valhalla mythology which I am a big fan. It has very nice graphics and awesome music which gets you to the epic mood of this slot. I believe this slot has many symbols since it has 6 letters, 6 high paying symbols, wild and bonus symbol. The wild when it substitutes doubles your win which is very nice. The highest paying symbol is Thor of course. I also like that when you click a symbol you can see how much it pays instantly without having to browse the pay table, I first saw that in this slot and it is very convenient.

When you get 3 or more bonus symbols, you win free spins and enter the Great Hall of spins where you can unlock and progress to the different modes of the free spins after playing a lot and winning many bonus rounds. All bonus features have different amount of free spins, with different multipliers and different features. I have managed to unlock them on few casinos that I play most of the times so you have to stick to a casino if you want to complete the Great Hall of spins. I really do not have a favorite free spin mode and every time I choose different mode.

Finally there is the Wildstorm feature which happens random and you can have up to 5 reels transformed into wild reels and win big. I have never been so lucky on this feature and the most reels of wild I have ever got is 3 .

Anyway I like this slot very much and have won big many times here, it is one of my favorites.

Thunderstruck 2 is 243 payways video slot from Microgaming company. It is very popular online video slot and I have seen many great screenshots from it.

I played this game at many casinos, but this game was not my first choice. For me it is not very popular and this is because I had no luck on it at all. I tried it many times for a couple hundred of spins but till now I don't have any great win. The design is good so as paytable. When I played it, I had some good wins during main game so I can't say anything bad about main game.

Free spins feature is trigger by at least 3 scatter symbols. Into free games you can find 4 different mode of features. Different numbers of spins and multipliers. But you will start at the beginning and after you trigger 5th features you can select next one. Many games from this software has set free spins feature like this one, but I don't like it. I prefer to see randomly like as at Jurassic Park game. And when I played Thunderstruck 2 the free spins feature was hard to trigger.

The game has also wild storm feature which is randomly awarded. This wild storm is completely the same as wild desire feature at Immortal Romance game. I remember last time when I hit this wild strom feature, I was playing at 0,6€ bet stake. I had two reels which turns into wilds. The second and third. At it paid me 2,7€ on 0,6€. So you see now, this is my luck at Thunderstruck 2.

Maybe I will play this game sometimes in the future, but I am not sure. I don't have luck on it every time when I play it. Otherwise it could be great game if you have lucky run on it. I will rate it with 7 stars here.
