Thunderstruck II Slot Review

1 People Voted!

Thunderstruck II is a Microgaming slot launched in 2010. The game houses 5 reels and 243 paylines with a 96.65% RTP. This non-progressive slot game also features wilds, scatter, mobile, multipliers, bonus games, free spins, and the Wildstorm bonus feature. This game has a jackpot of 8,000x your bet and is available for playing on both desktop & mobile.



Thunderstruck 2 is an online slot that has been around since 2010, which makes it a venerable name in the world of online gambling. And no, before you ask, it’s got nothing to do with AC/DC. The theme of this game revolves around Norse mythology, lightning, and magic.

More importantly, however, this is one of the most popular and probably best slots ever made. While that sounds like a strong claim, remember just how long Thunderstruck 2 has been around. Years go by, and thousands of players keep coming back to this little gem. Why? Keep reading our Microgaming Thunderstruck review to find out!

Thunderstruck II’s charms lie in the many special features it boasts. The core gameplay is fairly basic, though plenty of top slots have tried to copy it since.

You play Thunderstruck 2 on a 5×3 grid. The goal is simply to assemble identical symbols on adjacent reels, starting at the left-most reel and moving rightward. If you get 3 or more, you’ll win a payout based on the winning symbols. The rest of this game’s attractiveness comes from the various bonus features. We’ll get to those in a minute.

This sort of system offers 243 different ways to win, which makes for a fairly volatile game. It’s also a stark upgrade compared to the original Thunderstruck slot from 2013.

Casino Chick Best tips for Thunderstruck II Slot

  • The famous Wildstorm feature has an equal shot at appearing with any of your spins.
  • All of the Free Spin modes are a decent choice and none are obviously superior. However, Loki and Odin are somewhat more unreliable.
  • Thor Free Spins receive a multiplier on consecutive rolling reels wins.


There’s a lot of ground to cover when it comes to the special Thunderstruck 2 features, so we’ll try to be quick.

As always, Wilds can substitute any other symbol except Scatter. In this game, however, they also double the payout of any win they’re a part of. Occasionally, the Wildstorm feature triggers and turns entire rows into Wilds.

The Hammer Bonus symbol acts as a Scatter, which means it pays anywhere on the table. Additionally, three or more of these will trigger Thunderstruck II free spins. Each time you trigger free spins, new features are unlocked in sequential order. However, only one can be active per a single free spins cycle.

  1. The Valkyrie is the only option available in the first 4 triggers. She grants 10 Thunderstruck 2 free spins and multiplies all wins by 5.
  2. Loki grants 15 spins and the Wild Magic feature. Wild Magic symbols randomly transform up to 15 other symbols into other Wild Magic symbols. 2 or more also grant additional free spins.
  3. Odin is unlocked by triggering free spins 15 times. The One-eyed god can turn up to 2 symbols into Wilds with his ravens. These new Wilds also occasionally come with a 3x multiplier.
  4. Thor is also available after 5 free spin triggers. He grants 25 free spins and Rolling Reels. Essentially, new symbols tumble down and substitute winning ones. Multiple consecutive rolling wins also increase the multiplier.


In addition to the Thunderstruck 2 special symbols, there are 12 regular ones. The card symbols are the low-paying ones, as is traditionally the case. The Longship and Asgard are a bit better, while the symbols of the 4 aforementioned gods are where the big wins are.

You can play Thunderstruck 2 for real money at any Microgaming casino, and the RTP is always 96.65%. The only way to get the jackpot is by having a Wildstorm change all 5 rows into Wilds. Alternatively, you could stack up Odin free spins multipliers up to 5x.

what we like

  • Interesting Free Spins modes with long-term goals.
  • Way ahead of its time in terms of graphics and audio.
  • Solid RTP and overall profitability.
  • A classic and one of the all-time fan favorites.

what we don’t like

  • Some of the features are played out in this day and age.
  • Some players would have liked access to all the features from the start.


The jump from Thunderstruck 1 to 2 was interesting to see because it was evidence of how fast technology can improve. However, we never got a third sequel, and it seems we never needed one. The Thunderstruck II slot game continues to be an inspiration for some of the best slots still being made.

It’s an online casino classic and is worth checking out just to see what all the fuss is about. The ideas and features are not nearly as interesting as they were 10+ years ago, but the game holds up well.
