Thunderstruck Slot Microgaming

Thunderstruck is a 5-reel video slot develop by well-known Microgaming software provider that offers 9 ways to win. This exciting slot celebrates the God of thunder, Thor, who is in fact the game’s wild symbol. In addition  to Thor, once you start spinning the reels more symbols will appear such as rams which scatters, as well as Thor’s hammer, staffs and of course 9,10,J,Q,K and A symbols. Try it for free right here, or visit any of the Microgaming Casinos in our listings to play for real money.

Before setting of on this exciting adventure, you need to set your bet. Clicking on +/- under the coin icon regulates the coin size, while “Select Coins” adjusts the number of coins wagered. Players can also regulate the number of paylines by pressing “Select Lines”. “Spin” initiates the game and "Bet Max" automatically wagers the maximum sum and prompts the reels to start spinning. To play for a number of times without interruption, players need to click “Expert” and then “Auto Play”.

3 of the ram symbols will reward you with 15 free spins where all wins are tripled. What's more, these free spins can also be re-triggered. As a wild symbol, Thor will substitute in a winning combination and also double that win, making him worth a 6x multiplier in free spins.

With every line win, you can try your luck in the Gamble feature, where you can increase your winnings. If you guess the colour of the face down card correctly, your win is doubled, while guessing the suit quadruples the sum. However, wrong guesses result in the loss of the amount. Players can stop the gamble feature themselves and save their winnings by clicking “Co­lle­ct”.

So once again this is a 9 liner and if I am not mistaken this was the original 9 liner from Microgaming from which many clones were made. You get 5 reels, 3 rows, and 9 adjustable pay lines. In this game we have Thor being the Wild and doubles your win along with the sound of thunder to add that nice touch. There is a lot to like about a slot that is as simple as a 9 liner and Microgaming made a fine decision to choose this theme as one of its earliest releases. It is always nice to get the 15 free spins and that is done by getting 3 or more scatters, they could have given more spins if you get 4 or more but 15 is all we get but that is still a good number and opportunity is there to get further more spins by getting retriggers. And if you get 5 scatters you will get rewarded 500x Bet how good would that be? But that is quite rare but still 500x Bet for 5 scatters is better than what some slots give. Sure you can gamble your wins and I recommend doing that from time to time if you feel lucky at picking but stick to colors as it's a real 50/50 chance. Overall it is an old-school type of slot and I recommend you give it some spins to relive the way slots used to be.


Just like any other slot the free spins can be AWOL however put a few hundred spins through it and it will trigger them, but you only get 15 even if you get 4 or more scatters. Only 15? how about making it 20 free spins for 4 scatters and 50 free spins for 5 scatters. As for getting 5 wilds on a pay line is probably a 1 in 2 million chance, only saw a screenshot of it once on line 1 it was.

Ever reliable if you stay the course and not get too greedy too fast 😆 easier said than done. Starting with a $100 bankroll and 90c bets easily gets to $500 7/10 times. Resisting the urge to double the bet after each set of free spins


The game generally dies after 5 of a kind scatters or wilds in general play, and a 5 of a kind in free spins also generally kills the game. My advice, leave it for 2 hours before going back.

Thunderstruck, is a Microgaming video slot with 5 reels/9 Paylines based on the Nordic god of storms, Thor! Special features include Free spins and Wilds. On the reels, you will see: Thor himself/Scatter Rams/Thor’s Hammer/Horn/Thor’s Fist/Lightning/Mythical Castle. Compared to its sequel Thunderstruck II, the graphics pale in comparison.
