Microgaming’s Thunderstruck Slot Review

The Thunderstruck slot is a 5 reel 9 payline online slot powered by the impressive Microgaming and was created back in October 2003. It was original Norse mythology themed slot and that has earned cult status and caused a sequel (Thunderstruck II). It offers big wins courtesy of the Free Spins feature where you can win up to 30 free spins with all wins subject to a 6x multiplier. You can play from as little as 9p a spin to as much as £45 per spin on desktop, mobile and tablet devices.

Thunderstruck Theme/Symbols

The Thunderstruck slot machine has a Norse mythology theme and has a dark, cloud-filled sky in the backdrop. Based on Thor (the God of Thunder and son of Odin), symbols include A, K, Q, J, 10 and 9 royals. You’ll also see the horn of plenty (Cornucopia), lightning bolts, castles, Thor’s hand and Thor’s hammer on the reels.

The latter is the most rewarding giving you 83.33 times your stake for 5 on a payline. Thor himself is the wild symbol with 2, 3, 4 or 5 in combination giving you 1.11, 22.22, 222.22 and 1,111.11 times your stake. With winning combinations formed from left to right starting from reel 1, any win involving the Thor wild will double your win – it also replaces all symbols bar the scatter.

Free Spins feature

The Thunderstruck slot is all about the Free Spins feature – this is played if you get 3 more Ram scatter symbols anywhere on the reels. 2, 3, 4 or 5 scatters will give you 2, 5, 20 or 500 times your stake. 3 or more will reward you with 15 free spins.

Furthermore, all wins during the Free Spins feature are trebled as they are subject to a 3x multiplier. You can also trigger an additional 15 free spins (with a 3x multiplier of course) if you obtain 3 Rams during the feature taking your total to 30 free spins with a 3x multiplier. If a win involves the Thor wild symbol, you will theoretically benefit from a 6x multiplier.

Thunderstruck slot closing thoughts

Thunderstruck is a low to medium variance slot. However, it does offer good win potential as filling the reels with Thor wilds will result in a 10,000 times stake payout per spin. If you get a screen full of Thor wilds in the Free Spins feature, you’ll win an almighty 30,000 times your stake!

What I like about Thunderstruck is that it’s simple and fast-paced. It may look graphically dated but it’s become one of the most popular online slots of all time. The fact that the graphics are a little dated makes Thunderstruck more appealing to me than most newer slots – this game is still in the top 10 most played slot games for Microgaming casinos. The Thunderstruck slot RTP% is a decent 96.10% too.

In conclusion, the Thunderstruck game is iconic and paved the way for future Norse mythology themed slots – as a result, Microgaming released Thunderstruck II which is even better in my opinion.
