At Lucky Nugget Casino, we work hard to bring you a wide range of exciting slot games. In this review, we look in detail at the extremely popular Microgaming slot, Thunderstruck II. Find out more about the history of the game and its Norse theme. We also bring you a rundown of gameplay, bonuses, and any jackpots on offer. 

Overview Of The Theme

Thunderstruck II was released in 2010. As the name suggests, it’s the sequel to the much-loved 2003 release, Thunderstruck. While the original took the world by storm with a generous free spins bonus and powerful Norse theme, its sequel was seen as a vast improvement, packing in many more bonus features and taking advantage of the well-received 243 ways to win format.

As you can imagine, being a Norse-themed game, Thunderstruck II contains a plenty of Norse characters and gods. In this game, you’ll find:

Valkyrie: the entity that decides who lives and dies in battle, according to Norse legend

Loki: Thor’s step-brother and the bad guy from the Thor movies, made popular by the Thor film franchise, where he was played by Tom Hiddleston

Odin: father to Thor and Loki, and the leader of Asgard

Thor: protector of Asgard, who was played by Chris Hemsworth in the popular film series

Each of these characters brings the players a specific number of free spins. Read on to find out more.

The overall appearance of the slot is true to the theme, with a dark and stony background, creating an ethereal feel to the game. The atmospheric soundtrack also works well and complements the theme, creating a well-rounded slots offering. And while you won’t get next level graphics from Thunderstruck II – especially compared to more modern releases – the retro feel to this game only further adds to its charm.


Thunderstruck II is a 243 ways to win game with five reels, which also means no paylines. If you’ve never played this format before then we’ll explain. Essentially instead of using paylines, players are rewarded for landing symbols on consecutive reels, regardless of their position. Why 243? As each reel has three spaces, and there are five reels, you perform the sum 3 x 3 x 3 x 3 x 3 and you get 243. What does this mean for casual players? Simply, more ways to win.

You’ll find Thunderstruck II’s controls at the bottom of the screen. We found them to be a little confusing, but this could be due to the age of the game. They could have combined the coin value and coins section to bring a little clarity, but otherwise it works well.

Bets start from $0.01 per spin and reach a pretty impressive $15.00. While this might not be enough to entice the most serious high-rollers, it sure is enough to keep the casual players entertained. The jackpot, on the other hand, is enough to excite most, with a generous 1000x your original stake available.

You can also take advantage of the autoplay feature, which allows you kick back and relax while the computer does all the spinning.



If you’re hunting for bonus symbols, you need to be on the lookout for Thor’s hammer, which is the scatter symbol. Land three or more of these and you’ll trigger the Great Hall of Spins bonus, which involves the characters we introduced to you to earlier in the review.

Each character will provide you with a certain number of free spins, with each subsequent character unlocked as you continue to trigger the feature. It works like this:

Valkyrie from the 1st to 4th trigger: 10 free spins + a 5x multiplier on all wins

Loki from 5th to 9th trigger: 15 free spins + the wild magic symbol, which transforms random symbols into wild (Thor’s hammer symbol will award extra free spins)

Odin from 10th to 14th trigger: 20 free spins + raven feature, which turns symbols in 2x and 3x multipliers – land two ravens and you’ll
get a 6x multiplier.

Thor from 15th trigger onwards: 25 free spins plus a rolling 1x multiplier for every consecutive win (i.e. every time you win the multiplier increases by 1).

Alongside this, you could potentially trigger the separate Wildstorm bonus, which occurs randomly and will turn whole reels wild. If you’re extremely lucky, you could turn the whole screen wild, which provides some incredible payouts.


Thunderstruck II isn’t a progressive jackpot game, so unfortunately you won’t land any million-dollar payouts. If you’re looking for a great Microgaming progressive, we recommend you check out Mega Moolah. On the other hand, the maximum you can win is 1000x your stake, which is fairly standard for most video slots on the market (which aren’t progressives). With an RTP (return to player rate) of 96.6%, this game provides you with a fair rate, especially compared to a lot of modern slots which offer sub-par RTPs of 80% or less.

Why Should You Play Thunderstruck II?

If you’re looking for super-HD graphics, a modern and complex soundtrack and million-dollar jackpots, you might want to stay away from Thunderstruck II. If you’re more interested in solid gameplay, an exciting and unique bonus structure, and a game that has survived longer than most, then Thunderstruck II is a great choice. The Norse theme is also rather interesting, and with the creative license provided from this bygone religion, it has provided some interesting artwork and design.

Overall, Thunderstruck II is a well-rounded slot that we’d definitely recommend. If you already haven’t, check it out at Lucky Nugget Casino today.
