Thunderstruck II Slot: Review and Bonus to Play Online

Thunderstruck II Slot

The Thunderstruck II Slot is:

  • A solid 2010 title from Microgaming
  • A 5x3 Slot with 243 possible win combos

I’ve always been fascinated with Mythology-themed Slots, and Norse Gods are among my favorites.

Microgaming decided to release a sequel to the infamous Thunderstruck seven years after its release, and it looks amazing.

New graphics, advanced bonuses, and an RTP of 96% are enough for me to try it out for a solid spinning session.

Odin, Thor, Loki, and the Valkyrie are all about quality online Casino gameplay, hundreds of payline possibilities, and a progressive bonus feature to keep our chances high even when the game doesn’t favor us.

Let’s not waste time on introductions, but rather explore Thunderstruck II now.

Essential note: Fans of the original Thunderstruck Slot will be pleased to find the good old Viking atmosphere is still here. If anything, it is enhanced.

First Impressions on Thunderstruck II Slot

As I mentioned, Thunderstruck II is still the title hardcore gamblers know and adore. The design is easy on the eyes and doesn’t distract you from the spins.

243 ways to win can sound overwhelming at first, but this isn’t the case.

Each reel thumps heavily in place, symbols combinations can be tracked effortlessly, and the music is exactly right. Suspenseful, yet heroic melodies give the reels a mighty feeling.

You can match symbols in adjacent reels, left to right. It doesn’t matter where in the reel they are, which accounts for the added value element.

Essential note: As all classical titles, this one can be addictive, too. It is humble in the beginning and evolves when you go deeper into the game. So keep that in mind and be aware of your bankroll.

How to Play?

Thunderstruck II Slot has simple gameplay and payout structure. You don’t need to follow exact paylines, which makes it a breeze to play.

Be it a casual session or a dedicated all-nighter, you will hardly get tired with this one.

Before getting to spin for big wins, you need to adjust bet sizes:

  • Coin value can be adjusted with the -/+ buttons – the minimum is 0.01 and the max is 0.05.
  • The number of coins used for a spin varies from 1 to 10, right on the Coins tab.
  • You can choose the Bet Max option, too, but I don’t recommend it for real money play.

These settings equal to a min bet of £0.01 and a maximum of £15.

There aren’t any paylines to set, so we’re good to go.

Essential note: Thunderstruck II has an amazing AutoPlay feature. It is under the Experts tab, and lets you set the number of automated spins before stopping. In addition, you can choose to terminate your session after a certain profit has been reached.

How to Play Thunderstruck II

Getting three or more matching symbols on consecutive reels awards a win.

  • Low-value symbols – 9, 10, J, Q, K, A;
  • Medium-value symbols – Viking Longship and Valhalla;
  • High-value symbols – Valkyrie, Loki, Odin and the God of Thunder - Thor;
  • Special symbols – Thor’s Hammer is the Scatter and the Thunderstruck II Logo is the Wild;

What is more, any winning combo including a Wild gets double the winnings. I hit a Five-of-a-Kind 9s with three Wilds and my screen practically lit up. The music got more intense, and coins started flying all over the place.

Getting two Scatter symbols evens your bet, and 3,4, or 5 of them trigger Free Spins. More on that in the next section, as it is the most exciting bonus feature of the video Slot game.

Another neat add-on in Thunderstruck II – you can track your progress with Paytable Achievements.

The game ensures each of your combos is archived by marking it golden in the Payouts tab. I couldn’t get a full collection of those, but I got pretty close in about an hour of play.

[I][Essential note:[/I] Of course, the missing pieces from my quest were the highest value ones. You shouldn’t aim to conquer the game recklessly, as this can backfire badly. Have fun, enjoy it, but don’t waste away your bankroll just to gather 5 Odin symbols in place.

Bonus Features

As any respectable online Slot, this one strives to be unique. And I have to say, Microgaming has done an excellent job once again.

The bonus features here aren’t a ton, but they will surely bring excitement to your spins.

The Great Hall of Spins Feature

The Great Hall of Spins Feature

Landing 3 or more of Thor’s Hammer symbols enables one of the most modernistic bonus games. Your bonuses upgrade the more you trigger Free Spins.

  • 1st trigger introduces the Valkyrie. It gets you 10 FS on a 5x Multiplier.
  • 5th trigger gets Loki in the action. He has 15 Free Spins for you, along with a Wild Magic tile. It stays on Reel 3 and transforms other symbols into Wilds, too.
  • Odin reveals himself on the 10th trigger. He brings 20 FS and his two ravens, of course. Ravens can turn any symbol into a 2x or 3x Multiplier.
  • Finally, the 15th Free Spins screen shows Thor - 25 FS with the Rolling Reels bonus. Consecutive wins in this step increase your Multiplier up to 5x.

Yet another essential note: Getting more Thor’s Hammers can re-trigger free spins. Additionally, you get a 6x Multiplier if you land both of Odin’s ravens.


Wildstorm triggers on an entirely random principle – it may hit twice in ten spins, or it may stay hidden for an hour. However, triggering it can turn up to 5 reels (yes, all of them) into Wilds. Which equals an x1000 stake win.

Final thoughts

This one is among the most entertaining online Slots I’ve reviewed.

It is engaging, yet easy to play.

It keeps the traditional in the mix, but adds an amazing element of advanced gameplay. Thunderstruck II Slot has all the needed tools to make it to the Slots’ Hall of Fame.
