Thunderstruck II slot game review

Thunderstruck 2 slot

Thunderstruck 2 is among the most well known and popular slots of all time, and it became a smash hit when it was first released back in 2010. Microgaming really hit a home run with this game, and it quickly got a cult following that has only grown to this day. Themes inspired by norse mythology tend to be popular, and this is certainly no exception.

The main feature and attraction is The Great Hall of Spins feature, and you also have an exciting Wildstorm feature that is activated randomly while you play. This is most certainly a worthy sequel to the original Thunderkick, and once you start unlocking the free spin powers of the different norse gods, you’ll have a hard time keeping yourself away from this game.

Thunderstruck 2 RTP, variance & technical data

Before we take a deeper look at all the fun features this game has to offer, we shall reveal some relevant technical details for you:

  • RTP: 96.65%
  • Volatility/Variance: Medium
  • Layout: 5x3
  • Paylines: 243
  • Bonus features: Substituting Symbols, Free Spins, Multipliers and Wilds
  • Bets: 0.3 to 15
  • Max wins (coins): 2 400 000

The game has an RTP that’s a little higher than the average RTP out there, but nothing out of the ordinary. 96.65% Return To Player means that you can expect this game to pay out that percentage in the long run. The house edge of this game is thus 3.35%, which is quite decent.

The other thing to notice is that this is a medium variance slot. This makes it suitable for most anyone, and you don’t need to fear too much fluctuation on your bankroll as you play. The game will pay out decent wins on a regular basis, and this will keep you afloat as you wait for the big payouts.

Thunderstruck 2 Review

Thunderstruck 2 is the sequel to the highly successful Thunderstruck, and without taking anything away from the original from 2003, we have to say that the sequel, launched May 2010, is far better. In many ways, it’s an upgraded version of the original game, but it offers some exciting new features, and it allows you to win up to an incredible 2.4 million coins.

You still have 5 reels and 3 rows, but the number of paylines has increased from 9 to 243, giving it a more modern video slot feel. The first Thunderstruck looks a bit flimsy and cartoonish, compared to the more serious and heavy feel of the sequel. The latter suits the theme a lot better, and adds to the mystique and enjoyment of playing a game based on norse gods and mythology.

All the most famous nordic gods are represented here, and Valkyrie, Loki, Odin and Thor all play an important role in the massive Hall of Spins bonus feature. The stone carved symbols look really good on this game, and Thor’s hammer is, of course, the scatter symbol, while the Thunderstruck 2 logo is the wild symbol.

The Wildstorm feature appears at random times as you play, and makes the game unpredictable and fun. You get 1 free spin, and up to 5 reels can turn to wilds when this happens. Even just 4 wilds will give you a massive win, and we haven’t even started on the main feature yet - The Great Hall of Spins - which we shall discuss below.

Thunderstruck 2 bonus features

Thunderstruck II has one main feature, and that is the massive Hall of Spins free spins bonus game. In addition, you have the randomly triggered Wildstorm feature which turns a random number of reels into wilds. If all 5 reels turn into wilds, you’re in for a massive win.

Thunderstruck 2 free spins

Each of the 4 gods represent a different free spin feature, and you need to increase in levels to unlock new gods. You activate the feature by landing 3 or more Bonus Hammer symbols, and to unlock more gods, you need to trigger this feature a certain amount of times.


The Valkyrie is the first one you unlock, by simply landing at least 3 Thor’s Hammer scatters. You will get 10 free spins, and all your winning will be subject to a 5x multiplier. You can also activate more free spins if you land more scatters.


After having triggered the Hall of Spins feature at least 9 times, you have managed to unlock Loki. This gives you 15 free spins with a Wild Magic feature turning symbols into wilds on the middle reel.


After the feature has been triggered at least 10 times, Odin himself is unlocked. You’ll now receive 20 free spins combined with a Wild Raven feature. Odin’s Raven will turn symbols into 2x to 3x multipliers at random. If you land 2 of these, they will multiply into 6x.


The Thor feature is the final one to be unlocked, and that happens once you have activated the Hall of Spins at least 15 times. You now get 25 free spins with a Rolling Reels feature added. Every consecutive win increases the multiplier by 1x up to 5x, which means you can win some serious money when you reach this feature.

When all the gods have been unlocked, it’s up to you which one you chose next time you trigger the Hall of Spins feature. The game even remembers where you are on the progress bar, so you can pick up from where you left off last time.

Thunderstruck 2 jackpot (max win)

There is no jackpot to be found on this game, but you can still win some serious cash here. If you manage to get all 5 reels to turn into wilds in the Wildstorm feature, this will give you a win of 2.4 million coins. This equals $600,000 when playing with maximum stakes. Not bad at all for a medium variance slot.

Thunderstruck 2 mobile & tablet

You can play Thunderstruck 2 on any mobile and tablet, and this give you great freedom to take this game with you wherever you may go. As long as you have an iPhone, iPad or Android device handy, you can play with the norse gods and go for the big wins.

SlotCatalog verdict

When it comes to movies, the sequel is usually worse than the original, but when it comes to slot games, this is often not the case. A lot happens in technological development in 7 years, and it shows when you compare Thunderstruck 2 with the original. The sequel is a far better game in our view, and much more fun to play also.

You can win an enormous amount of money with the Wildstorm feature, and the Hall of Gods free spins is pure genius. Having the ability to come back to the game and continue where you left off is a great innovation, and locking up these different gods is as rewarding as it is fun. We highly recommend you try this game as soon as possible, and you’ll be sure to have a great time, like so many other players out there.


  • Multi-level massive free spins feature
  • Unlock 4 different gods and their superpowers
  • Medium variance fits most people
  • Wildstorm with a max win of 2.4 million coins


  • Graphics could have been even better
  • Missing some cool animations
