Microgaming’s Thunderstruck II Slot Review

Thunderstruck II is one of the most popular online slots of all time. Released in 2010, this 5 reel, 243 ways to win game has a Norse mythology theme and can be played from 30p to £15 a spin on all devices. It benefits from a randomly-activated Wildstorm feature where up to 5 reels can turn fully wild. It’s all about The Great Hall of Spins where you can play 4 free spins features based on Thor, Odin, Loki and Valkyrie. They offer you 5x multipliers, Wild Magic symbols for random wilds, Odin’s Ravens for multipliers up to 6x and Rolling Reels with consecutive wins increasing the multiplier up to 5x. You can win a whopping 8,100 times your stake via the Wildstorm feature or each Valkyrie free spin!

Thunderstruck Theme/Symbols

With an epic soundtrack playing as you spin the reels, the graphics/animations are a little dated as Thunderstruck II was released in May 2010 – saying that, it has a nostalgic charm to it. Symbols on the reels include A, K, Q, J, 10 and 9 playing cards as well as viking longships. You’ll also come across Nordic gods Valhalla, Valkyrie, Loki, Odin and Thor – the latter is the most rewarding standard symbol giving you 16.67 times your total stake.

The Thunderstruck II logo is the wild symbol and substitutes for all other symbols bar Thor’s Hammer (which is the scatter). When part of a win, it doubles your payout. 5 wilds on a payline will give you 33.33 times your stake – if you were to get 4 Thor symbols and a wild, you’d also win 33.33 times your stake. You will form wins by getting matching symbols from left to right.

Wildstorm feature

The Thunderstruck II casino slot comes with a randomly triggered Wildstorm feature – here, up to 5 reels can turn fully wild. This would mean you would pocket a cool 1,000 times your total stake.

The Great Hall of Spins features

Thunderstruck II is all about The Great Hall of Spins – this is accessed by getting 3, 4 or 5 Thor’s Hammer scatters. 2, 3, 4 or 5 scatters anywhere in view will give you 1, 2, 20 or 200 times your total stake by the way. This is a multi-level free spins feature – with 4 on offer, you can access various levels once you trigger The Great Hall of Spins a certain number of times:

  • Valkyrie feature - this is available from the 1st trigger and gives you 10 free spins with a 5x multiplier. The good thing is that you can retrigger more free spins if you’re lucky.
  • Loki feature – this is available from the 5th trigger and gives you 15 free spins. It benefits from the Wild Magic feature – look out for Wild Magic symbols on reel 3 as this randomly transforms symbols into extra wilds. You can also win 1, 2, 3 or 4 more free spins for 2, 3, 4 or 5 scatters.
  • Odin feature – this is available from the 10th trigger and rewards you with 20 free spins. The Wild Raven feature comes into play as Odin’s Raven symbols can randomly turn symbols into 2x and 3x multipliers. If both ravens land, you’ll benefit from a 6x multiplier.
  • Thor feature – this is available once you enter The Great of Hall of Spins 15 times. You’ll get 25 free spins with the Rolling Reels feature – when you get a winning combination, the multiplier increases to 2x. Subsequent wins will increase the multiplier up to 3x, 4x and finally 5x.

Thunderstruck II closing thoughts

Once you’ve entered The Great Hall of Spins 15 times or more, you can choose any of the 4 features you fancy – there’s a progress bar to show you how many times you’ve entered it. Medium variance, the biggest wins will come from the Wildstorm feature and Loki feature (with the 5x multiplier) which can result in an 8,100 times stake payout per spin!

Thunderstruck II may be old but it’s still very much-loved today – Microgaming has since released Immortal Romance which has a vampire theme but uses the same game engine. It’s more volatile though with wins of up to 12,150 times your stake on every free spin in the Troy feature.
