Thunderstruck is one of the most popular online slots in the world, with millions of plays since it was first launched back in 2003. Based on Norse mythology, this brightly-coloured epic, revolutionised the genre when it was released and has since inspired many similarly themed slots. In this Thunderstruck slot review we’ll look at the features that make this such a standout title, the features that have helped Thunderstruck become one of the biggest and most iconic titles in the Microgaming portfolio.


  • Game Type: 5 reels and 9 paylines video slot
  • Return to Player (RTP): 96.1%
  • Volatility: High
  • Theme: Norse Mythology
  • Release Year: 2003


Thunderstruck has a betting range of between 1 and 5 coins per line, with a maximum bet of 45 coins. You can choose to bet on anywhere from 1 to 9 lines and anywhere from 1 to 5 coins per line, leading to a betting range that goes as low as 0.01 and as high as £45. The Thunderstruck jackpot is tied to the Thor Wild and pays out 10,000x your stake, or £45,000 if you place the maximum bet!


Thunderstruck has 9 paylines that pay from left to right. See below to learn more about playing this iconic online slot:

  • Symbols: The Thor Wild symbol is the biggest in the game and begins to payout when just two are revealed in succession. This is followed by Thor’s Hammer, the Wooden Staff, the Castle, the Lightning Bolt, and the Horn. There are also a number of standard playing card symbols returning anywhere from a 2x win to a 125x win.
  • Bonus: The Ram Scatter symbol unlocks 15 bonus spins when three, four or five of these appear anywhere on the reels. These Scatters also payout an instant win that increases significantly for every additional one that is revealed (a minimum of 2x and a maximum of 500x). Additional bonus spins can be unlocked during those initial 15 spins.
  • Gamble: The “Gamble” button becomes active after every winning spin. To play, simply press the button and then choose between a Double or Nothing, whereby you bet on whether the card will be red or black; or a 4/1 bet, where you guess the suit of the card. You can keep gambling your winnings until the maximum win has been claimed, but you’ll be sent right back to the game screen with nothing if you lose.


Thunderstruck is one of the best online slots that Microgaming have created and for many years it was one of the most played slots online. It was first launched back in 2003, but its visuals and features were ahead of its time and that has helped Thunderstruck to remain as one of the most popular slots around. Thunderkick works for both desktop and mobile and was actually one of the first slots to be adapted for mobile play. It’s quick, it’s smooth, and it’s exciting—everything a slot should be.
