Very good


Thunderstruck first appeared in in 2004, and although there has been a successful sequel, it remains a very popular game in its own right. The theme is based on Norse mythology, and it’s a fast-paced game with a valuable free spin bonus feature.

How To Play

Thunderstruck is a 5-reel, 9 payline game (like the Big Kahuna) where all the wins pay left to right.  Coin values range from $0.01 to $1.00, and you can play a maximum of five.  With 9 payline, the maximum bet is $45.00, but the game can be played for as little as $0.01 per spin.

Game Symbold and Paylines

  • Thor is a wild symbol that substitutes for any symbol (except scatters)
  • Thor doubles any win
  • 5x Thor symbols = payout of 10000x coins (up to $10,000)
  • Ram is the scatter symbol, and 2x or more pays anywhere on any reel
  • 5x scatter = payout of 500x coins (up to $500)
  • 3x, 4x, or 5x of the scatter symbol activates the 15x free spin feature

15x free spin bonus: Triggered when the scatter symbol appears 3x, 4x, or 5x, this is an exciting feature as all wins are tripled (and during which you also have the chance to win a further 15x free spins).  It is a good approach in this game to play the maximum number of paylines because all bets and lines played are retained during the free spins.

Gamble Feature: After winning you can opt either to pick a colour card (which pays 2x your winnings) or pick a suit (which pays 4x your winnings).  You can gamble your wins up to four times, but a loss in this feature loses all of your winnings from that spin.

Graphics and Sounds

The game’s theme is based on Norse mythology, featuring the God Thor and other ancient Nordic images, such as castles, axes and lightning bolts. The graphics are bright and colourful with the different symbols being easily distinguishable.  The background music (which can be muted) features a primitive drumbeat mixed with the sound of swirling winds and sea, while rapid hoofbeats during the free spin feature help to heighten the excitement.  Each spin is accompanied by a sound of a harp being strummed, a winning spin prompts a trumpet-like flourish, while 2x or more of the scatter symbol triggers a burst of thunder and lightning.


The maximum jackpot available on Thunderstruck is 10000x coins if you line up 5x Thor symbols, so it’s possible to win a jackpot of up to $10,000 on any spin during regular play.  A $30,000 jackpot is possible when playing the 15x free spin feature, as all wins during this bonus round are tripled.  You don’t need to play any set number of coins or playlines to win access to the free spins feature, but it should be remembered that all bets and lines played are retained during the free spin round.

Other than the 5x Thor jackpot, Thunderstruck offers numerous other great payouts such as 4 x Thor winning 2000 coins or $2000.

Special Features

The game’s special features including wild symbols, scatters, free spin bonus and the gamble feature make Thunderstruck an enjoyable and potentially lucrative game offering good-sized payouts to be won, as well as opportunities to increase the size of any win
