thunderstruck-2-slot-base-game

With a Norse mythology theme, Thunderstruck 2 focuses on the Norse God of Thunder (Thor). You join Thor on his journey with other ancient Norse gods in the realm of Asgard. With an epic soundtrack playing as you spin the reels, the graphics and animations are actually high definition.

Despite being originally released in May 2010, developer Microgaming has remastered the game with the latest version available from the 10th of December 2020. The new version has enhanced sounds and animations and a modernised layout.

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. Thor is the most rewarding standard symbol giving you 16.67 times your total stake for 5 in combination.

The Thunderstruck 2 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. Here’s a table of the payouts for the top symbols:

thunderstruck-2-slot-the-great-hall-of-spins-features

Thunderstruck 2 is all about The Great Hall of Spins features. 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 features once you trigger The Great Hall of Spins a certain number of times. There is a progress bar to show you how many times you’ve entered it. Here’s what to expect:

Valkyrie Free Spins 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 to give you 20 free spins in total. The max win per free spin is 1,383 x your stake.

Loki Free Spins 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. The max win per free spin is 8,000 x your stake.

Odin Free Spins 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. This can lead to 3,320 x stake wins per free spin.

Thor Free Spins 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. The max win per free spin is 1,383 x stake.

Originality








The Thunderstruck 2 slot may be old but it’s still much-loved by slots and casino players. Graphically, it has been revamped by Microgaming (in late 2020) and became the standard for many slots that tell a story. The soundtrack is particularly good.

It’s all about The Great Hall of Spins as you can access the 4 free spins features. Once you’ve triggered it 15 or more times, you can opt for any free spins feature you fancy.

The Loki Free Spins feature is the best one as it offers the biggest win potential, up to 8,000 x stake on every free spin. The random Wildstorm feature can also deliver the same payouts.

Thunderstruck 2 may be old but it’s still 1 of the best online slots ever. Due to it’s overwhelming popularity, Microgaming has created various Thunderstruck slots each with their own appeal:

The best thing about Thunderstruck 2 is that it paved the way for the Immortal Romance slot. With a vampire theme, it uses the same game engine/mechanics. It’s more volatile though with max wins of up to 12,150 x bet on every free spin in the Troy feature.

Pros
  • 1 of Microgaming's most loved slots
  • High RTP rate of 96.65%
  • Provided the platform for Immortal Romance
Cons
  • Graphics a little dated
