Thunderstruck II Slot Review

Thunderstruck II is a video slot brought to you by Microgaming. The game was launched in May 2010 and has become of the most played slot games online today. It features 5 reels and 243 ways to win (paylines) and you can play up to 300 coins at once (up to £15 a spin). It has a Norse mythology theme which means it’s based on Nordic gods such as Valkyrie, Loki, Odin and Thor.


Thunderstruck II has a small 1,000 coin jackpot though which is disappointing. Apart from this, you’re in for a real treat. Look out for the Thunderstruck II logo as this is the Wild symbol and substitutes all symbols except for Thor’s Hammer symbol. The wild symbol won’t apply during the Wildstorm feature – this is a feature that is triggered randomly. This feature will earn you 1 free spin with up to 5 reels turning wild. If you get 4 or more wild reels, prepare yourself for a huge win.

The main feature of Thunderstruck II is The Great Hall of Spins feature – this consists of free spins with a multi-level element. To gain access to the feature, you need to get 3 or more Bonus Hammer symbols. You will notice there are 4 levels to the bonus feature which you can trigger by getting into the bonus round a certain amount of times.

First up is the Valkyrie feature which is triggered on your first to fourth feature triggers. You are rewarded with 10 free spins with all wins multiplied by 5 (5x multiplier). The good thing is that you can retrigger more free spins if you’re lucky.

Then you have the Loki feature which is available from the fifth to ninth feature triggers. You are awarded 15 free spins with the Wild Magic feature. The Wild Magic symbols on the middle reel transform symbols into additional wilds.



The Odin feature is playable on the tenth to fourteen feature triggers. You will get 20 free spins as well as the Wild Raven feature. Odin’s Raven symbols can randomly turn symbols into 2x or 3x multipliers. Get 2 and you will benefit from a 6x multiplier.

Finally you have the Thor feature which is available from the fifteen feature trigger onwards. Here you receive 25 free spins with Rolling Reels. Consecutive winning spins increase the multiplier from 2x to 3x to 4x to 5x. This means you can potentially getting a 5x multiplier on every single free spin.

Once you trigger all 4 levels, you can choose whichever level you fancy once you go back to the Great Hall of Spins feature. The game has a memory meaning you can pick up where you left off (there’s a bar measuring your progress). Even though this is a medium variance slot, it’s well balanced and can produce some huge wins. I really like the Thor feature as Rolling Reels can give you a huge return – it’s no coincidence the Rolling Reels feature is found is other Microgaming slots such as the higher variance Immortal Romance and blockbuster Avalon II.

    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.

    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.

    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.

    I really enjoy most of these 243 way slot games, they play very differently to games with fixed lines, and it can be really disheartening that so many spins result in a win that is just way below the value of how much you paid to spin the reels – this one in particular, the base game has very little potential so your going to be spending most of your time praying on hitting the scatter symbols if you want to see a decent win. Like many of these games, there are multiple features to unlock as you get into the feature mode multiple times. After playing this game for along time I’ve settled on the “Wild Magic” mode as my favourite, as, whilst it has just as much potential to disappoint horribly as the other modes, you have to love it when that “Wild Magic” symbol drops in the middle and you wait to see how many spaces it will convert to wilds, and are doing the maths in your head to see just how big a hit it could be. It's so exciting when you realise its made you a massive five of a kind, though not so exciting when it replaces wilds already on the reels with just another wild. Slots have a habit of being annoying like this though, don’t they!!

    Thunderstruck II is a video game which is by the way one of my all time favorites. This video slot is powered by Microgaming and it has 5 reels and 243 paylines. I played this game recently on 32Red casino. That day I was only focused on this game, where I made a deposit of 25$ plus the bonus I got, so I was ready for the game. I started of with a 0.30$ bets per spin and after about 30 minutes I was raised for about 40$. This amount of payout was given to me by my good friend Loki in the bonus game. The next 30 minutes I played with a 0.90$ per spin, actually not played as much as just left the game with 100 FS on its own. But when I got back, didn't even manage to hit the bonus game and my balance was cut down to about 20$. So it was again time for some safer bets, so yet again I placed the bet of 0.30$ per spin and after a while managed to get to not so amazing 50$, then I decided to leave the cash there and try again tomorrow. For the actual game there are wild symbols that substitute for anything except bonus symbol. This feature helped me a lot of times with the five of a kind win especially since it doubles it. Then there is bonus symbol that activates the great hole of spins if 3 or more appear. I managed to get to Odin, but then my luck disappeared. Also you have Valkyrie, Loki and the last is Thor. Then there is also a Wild storm feature that I manage to trigger several times with not so special winnings, was quite a lot disappointed by the outcome, but it will be better next time. Like they say, you can't win them all. Overall really interesting and fun game with lots of features to play or trigger. A solid 9/10!
