Thunderstruck II Slot Review

Thunderstruck II is a slot brought to you by Microgaming. It has become 1 of the most played slot games ever. It features 5 reels and 243 ways to win (paylines) and you can play from 30p to £15 per spin across all devices. It has a Norse mythology theme which means it’s based on Nordic gods such as Valkyrie, Loki, Odin and Thor.

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, 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. The game comes with a randomly triggered Wildstorm feature – up to 5 reels can turn fully wild which would result in a 1,000 times stake win.

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 feature 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.

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.
