Welcome to Thunderstruck

Thunderstruck is one of the most popular iGaming titles by Microgaming, and it's also one of their first ones. This Nordic mythology-based online slot machine has been ruling the online casino leaderboards for several years, it's a really used and popular theme.

The classic gaming structure of 5 reels and 3 rows is followed in Thunderstruck. Although it has been quite some time since it entered the market, it still features a very rewarding casino free spins round that can give you up to 30 free spins.

The unbelievable 30,000x max jackpot is one of Thunderstruck's most attractive features, and there are not many iGaming titles that offer such big payouts. The wild symbol is also very powerful, and it will double the payout you get when you land a combo.


Nordic visuals and theme of Thunderstruck

Thunderstruck follows a central Norse mythology-inspired theme that influences most of the game's graphic elements. Thor is one of the most popular Nordic gods and he too plays an important part in Thunderstruck.

The mythology theme, particularly Nordic mythology, is very popular. You will find many iGaming titles based on them, like God of Thunder and Son of Odin.

The background is a dark view of a cloudy sky where thunder is imminent. The symbols are also designed according to the theme and include castles, thor's hammer, lightning bolts, and thor's hand. The hammer and his hand are the most rewarding symbols, giving you payouts up to 83.33x.

If you get the hole grid with either of the 2 highest paying symbols, you'll be rewarded a 750x payout. Thor himself is the wild symbol, and can also form combos on his own, giving payouts increasing up to 1,111.11x. This wild symbol will help you land winning combos by substituting all the regular symbols.

Thunderstruck - How To Play

Thunderstruck is a perfect choice when new in the world of online slots. The game lets you set a very low bet and is a popular choice among beginners. You can set a bet as low as €0.09 per spin, which is low and will let you spin the reels a decent number of times and fits a small gambling budget.

After setting the bet amount, press the spin button on the bottom right side of the game screen. Keep spinning the reels, and you'll collect wins of different sizes. If you find manually spinning the reels a bit hectic, you can use the auto spin feature.

The controls are very simple and you will become a betting spin master in no time.

Special Features and Modifiers

There are 2 different special features in Thunderstruck. There is a fantastic double wild feature, along with the free spins round, and you can win them with some multipliers.

Double Wild Feature

This bonus in Thunderstruck is activated when you land the Thor wild symbols. Any win with the help of the wild symbols will result in a double payout. For example, if you were getting a payout of 10x from a specific combo, you'll get 20x.

Free Spins round

The game's main attraction is definitely the free spins round. You enter the bonus round after getting 3 or more Ram scatter symbols.

Getting 3 Rams will give you 15 free spins, and you'll also get a 5x multiplier for your wins. Like this, the value of the multiplier keeps increasing with the number of scatters you land on the reels. You will get a 500x multiplier for landing 5 scatters, along with the usual 15 free spins.

The great thing about the free spins round is that you can retrigger it if you land enough scatters during any of the free spins. If you get 3 Rams Scatters during a free spin, you will get 15 more free spins with a 3x multiplier.

The wild symbols become more powerful during the free spins, and using a wild symbol to land a combo will give a 6x boost to your payout. Also, the 10,000x payout you get for a screen full of wild symbols also become even more rewarding during the free spins. You can win a 30,000x payout for 15 wilds during the free spins, which is just incredible.

The lighting verdict of Thunderstruck

Thunderstruck is a unique game with a perfect blend of classic simplicity and power-packed special features. The whole idea of a Nordic theme based on Thor is very engaging and exciting. Different visuals like the background and the symbols are well designed.

Launched back in 2003, Thunderstruck has been amongst the top slot machines for around 2 decades and it's a pretty big achievement. Microgaming must be proud and deserves all the praise.

Impressed by the success of the slot and the love it got from the players forced Microgaming to create its successor, Thunderstruck 2, which is also really great. There are many graphic improvements in the sequel, but the original game is still an undefeated winner when it comes to the jackpot amount.

You can win up to 30,000x on a single spin in Thunderstruck, which sounds unbelievable. Considering the medium to high volatility rating, it is a superb jackpot amount. Playing the game with a high bet can result in some fantastic payouts.

We highly recommend Thunderstruck and you should definitely give this game a chance. You can try it here at through the demo version.
