Thunderstruck is without doubt one of the most popular online pokie in most online casinos.

Thunderstruck has been in existence since 2004 and has a 95% expected return. Thunderstruck is five-reel, and 9 pay line slot developed by the biggest game producer in the world.


Thunderstruck is available in most Microgaming powered online casinos both in an online flash version and a native download version. Ironically, the browser based flash version feels less chunky and more playable than the native counterpart.

Thunderstruck has been there since 2004, and although it has an excellent performing sequel, it remains a favourite to majority of slot fans. The slot adopts a Norse mythology theme with several themed animations and symbols.

The graphics are rich and high quality like we would expect for any slot powered by Microgaming. The symbols are easily distinguishable from each other. The soundtracks in use are adopted from the game and players can toggle between mute and sound on!



Thunderstruck has a decent a coin value range that will accommodate both the budget players and the high rollers alike. The bet value ranges from $0.01 to $1.00, with the maximum play being $5 per line meaning the maximum bet is $45.00, and the minimum being $0.01 per spin.

Game Symbols and Pay lines

Thor plays wild and can replace any other symbol except the scatter symbol. Ram is the scatter symbol in Thunderstruck and thus you should look forward to this symbol. If you manage to land five Thor symbols, you get 10000x coins that can be up to $10, 000 dollars depending on your bet size. If you land five scatter symbols, on the other hand, you get 500x free coins which translate up to $500.

Free spins Bonus

When you land more than three scatter symbols, you stand a chance to make big winnings. In this bonus round, you get your winnings tripled and at the same time you stand a chance to get 15 free spins to increases your chances of bigger wins. The higher your bet, the higher your wins will be since the bonus coins are dependent on the amount wagered.

Gamble Feature

If you feel lucky enough, you can decide to gamble your winnings. You will be presented with a face down card, and you will need to either guess the colour of the face-down card or a suit from which the card has been extracted. Depending on you gamble, you can get your winnings doubled or quadrupled for the colour guess and suit guess respectively. If you guess unsuccessfully, you lose all your winnings.

Jackpot feature

The maximum jackpot is triggered when you line up five Thor symbols on all the reels. This is rewarded with 10000 coins that are equivalent to approximately $10,000. This makes the game unique as compared to other slots. It is very rare to find a slot offering up to $10,000 in regular play. The jackpot can go as high as $30,000 when playing the 15 times free spin bonus feature since all the wins in this round are doubled!
