How to play

Thunderstruck is a little different to most other Microgaming slots as it only has nine paylines. Before you hit spin you will need to choose the size of your bet and how many paylines you want to play. The coin size ranges from 0.01 to £1, or if you want to bet the maximum amount for the best chance of winning, you can just click on Bet Max.

Once you’ve spun the reels you’ll be faced with a whole range of potential outcomes. Three or more matching symbols will get you a payout and access to the ‘gamble’ feature. This bonus feature shows you a face down card and you need to either guess the color or the suit to double or quadruple your winnings. Of course if you guess wrong, you will lose the lot so choose carefully.

With Thunderstruck there are also a few special features including a wild symbol that can be substituted for other symbols to give you a winning combination. If you get five wilds across an active payline you will hit the big jackpot of 10,000 coins.

Three or more of the scatter symbol and you will get into the free spins bonus game, which gives you more chances to win and have fun in the process.


Thunderstruck may not be a fancy progressive like some of the other Microgaming hits but it still offers a very nice maximum payout of 10,000 coins if you get five wild symbols in a row on an active payline.

There are also some other smaller jackpots on offer here too, and these can be won by getting other combinations of symbols. The Thunderstruck free spins bonus gives you 15 free spins during which the winning spins are trebled – this will give you around 30x your initial bet if you are lucky and potentially more as the free spins can be retriggered giving you even more multipliers.

Thunderstruck casino game is a high volatility slot, which means that while there are some great payouts on offer, they don’t come too often. Still, this is part of what makes this game so compelling and exciting. You never know when the big payout might come but like Thor’s lightning it will be out of the blue.

Special Features and Bonuses

Thunderstruck’s special features and bonus rounds are what make this game really stand out from the crowd, and they also give players the opportunity to land some fantastic payouts.

When you start playing the game you will probably notice that you can choose to play on auto play, which will automatically spin the reels for a set number of spins while you get on with other things. There is also a quick spin feature that speeds everything up, great if you’re the impatient type.

When it comes to the game itself the free spin round is one of the most exciting features you’ll encounter. If you get three scatter symbols (the rams) anywhere on the reels you will enter the free spins bonus game. This gives you 15 free spins with a 3x multiplier and can prove very lucrative indeed.

The gamble bonus feature is also a nice touch for the brave who feel like risking it all to double or even quadruple their winnings. After each regular win you can choose to guess the color or suit of the face down card. If you get it right you increase your winnings, if you get it wrong you lose it all.
