How to Play

Bets per spin in the Thunderstruck slot game are between 9p and £45. Winning combinations are formed by landing 3 or more matching symbols across a payline, starting from the leftmost reel.

The symbols on the reels of this game are:

  • 9
  • 10
  • J
  • Q
  • K
  • A
  • Horn of plenty
  • Lightning bolt
  • Castle
  • Thor’s staff
  • Thor’s hammer
  • Thor wild
  • Ram scatter

Jackpot

In the base game, the Thor wild symbol is the highest value symbol on the reels and can award up to 1,111x your bet for 5 in a winning combination. The maximum win available in Thunderstruck is 30,000x and this is available during the free spins feature.

Special Features

There are 2 special features in the Thunderstruck slot game including a double wild and a free spins feature.

Thor is the wild symbol and he can replace other symbols on the reels to help form new winning combinations and potentially award larger winning combinations. What’s more, Thor is a double wild symbol, so any wins that he is part of will be doubled.

The ram is the scatter symbol and landing 3 or more on the reels will trigger the free spins bonus round plus an instant prize:

  • 2 ram scatters – 2x
  • 3 ram scatters – 5x
  • 4 ram scatters – 20x
  • 5 ram scatters – 500x

Players are awarded 15 free spins and all wins during this round are multiplied by a 3x multiplier. If during this round another 3 ram scatter symbols land, an additional 15 free spins are awarded. If a Thor wild is part of a winning combo, this 2x multiplier is combined with a 3x multiplier to award a 6x multiplier. If the screen becomes filled with all wild symbols, players can look forward to a trebled win of 30,000x.

Graphics and Sounds

Thunderstruck is an older game from Microgaming and Games Global, so the graphics are not as high-quality as you would expect from newer releases. However, this game is a classic and one of the first major Norse mythology themed games to enjoy. The stormy sky acts as the backdrop to the reels, while on the reels the high value symbols include Thor, his hammer, his staff, lightning bolts, rams and horns. The low value symbols are the standard playing card symbols. The soundtrack is a little underwhelming as it is mostly the sound of the slot reels spinning that you will hear.

Conclusion

Thunderstruck is an iconic slot game and a must spin slot for most online slot players. While its sequel games are ultimately more popular due to better quality graphics and bigger bonus features, this is still the original slot that started it all and is worth a spin. If you enjoy playing Norse mythology themed slot games and prefer simple bonus features, then this could be a great option for you. While the free spins and wilds are simple, they offer huge wins of up to 30,000x your stake which is more than what you will find in most modern slots.
