Design, Symbols and Graphics

As I said above, the Thunderstruck slot has a Norse mythology theme, with Thor being in the focus of the gameplay. The background is simple, featuring a sky with dark clouds. The game has basic graphics and animations, which is understandable given the fact that its release date is in 2004.

The reels are spinning really fast and in a style that is unique to a number of Microgaming slots. As for the symbols, you will find a plethora of symbols that have to do with the Norse god of thunder Thor - hence the name Thunderstruck slots. On the reels, you will see two tiers of symbols - the low-paying card symbols and the high-paying picture symbols.

The former includes the cards nine to ace, which are depicted in a thunderous background that is about to crack and crumble. The latter category of symbols includes the gyalhorn, a thunder, a sceptre, Thor's hammer and his castle.

What is more, the Thunderstruck slot has one of the most powerful symbols in the world of online slots. I’m talking about the Thor wild symbol, which doubles any winnings when it substitutes any other symbol, except the scatter. 

But, there is more to this symbol and I’m going to let you in on the surprise very soon! Finally, the rams symbol is the scatter and it triggers the Free Spins bonus.

RTP, Variance and Payouts for Thunderstruck Slot

Gameplay and Features on Thunderstruck Slot

Don't be fooled by the fact that Thunderstruck is an older slot - it's filled with fantastic features which make it way beyond its time! Let's see how to take advantage of them.

Double Wild Feature

I’ve already mentioned that Thor acts as a wild symbol in this game. Well, when you form a winning combination with the Thor wild, the symbol will double your payout! This is known as the Double Wild feature. In other words, forming a 5-of-a-kind winning combination with Thor symbols will give you a 1,500x stake payout.

Free Spins Feature

You can trigger the Free Spins feature by landing 3 or more scatter symbols on the same spin. When this happens, you’ll win 15 free spins.

During the Free Spins feature, all wins are subject to a 3x multiplier, which is fantastic. This means that, if you form a win with the Thor symbol during the free spins, it’ll be doubled with a 6x multiplier!

The Free Spins feature can be retriggered by landing 3 or more scatters during the feature. Then, you’ll win additional 15 free spins.

Our Verdict

For a game released in 2004, Thunderstruck is way more than brilliant! So, it’s not surprising to me that the game is still among the most popular slots at many online casinos. The key to winning big here is from the Thor wild symbol, especially if you form a win with it during the free spins. I liked this slot a lot, what about you?
