Thunderstruck 2

Thunderstruck II is a Norse mythology-themed title from Microgaming, and it’s the sequel to the much-loved original Thunderstruck online slot.

It invites you to come and claim prizes courtesy of ancient gods such as Thor, and it also boasts some brand-new features that were lacking in its predecessor. For instance, you can now enjoy Paytable Achievements, which are earned by completing all possible winning combinations for each symbol. And, as you unlock the different symbols, the paytable changes to gold. But, as well as allowing you the occasional congratulatory slap on the back, the Paytable Achievements Feature also makes it possible to keep track of your previous wins, which is useful if you like to try out different strategies or review your most successful playing sessions.

The software house behind Thunderstruck II is none other than the multi-award-winning company, Microgaming, which has enjoyed significant success over the years with online slot games such as Game of Thrones and Mermaids Millions.

And, if you’ve ever played the Immortal Romance online slot by Microgaming, you may notice certain similarities between the bonus features. Whereas Thunderstruck II boasts The Great Hall of Spins where you can unlock more bonus options the more you trigger the feature, Immortal Romance contains a similar bonus called the Chamber of Spins. But, only Thunderstruck II boasts a Wild Storm, Wild Magic and Wild Raven features. So, if you’ve yet to play it, and you’re looking for an affordable online slot that allows for player progression and comes with several unique bonuses, make sure you try it today!


Rather than using traditional paylines, the Thunderstruck II online slot allows you to create winning combinations in 243 different ways.

There are fourteen paytable symbols which include the four gods (Odin, Thor, Loki, and Valkyrie), Thor’s hammer, the Thunderstruck II game logo, Valhalla, and five playing card symbols (10, J, Q, K, and A).

You can change the size of your bet using the line bet plus and minus buttons as well as the “Coins” setting, and to see how much money each symbol awards, you simply click on the “View Pays” button.

Wild Symbol

In the Thunderstruck II online slot, the Thunderstruck II game logo acts as the wild symbol. It acts as a substitute symbol, which means that it can replace any symbol except for the scatter to help create a winning combination. It also conveniently doubles the value of any win that it contributes towards.

Scatter Symbol

The scatter symbol in the Thunderstruck II online slot is Thor’s hammer (which has the word “BONUS” written across it). It awards scatter wins, and can also open The Great Hall of Spins.

Bonus Round

The Great Hall of Spins is the most notable special feature of the Thunderstruck II online slot, and to open it, you need three, four or five scatters to land anywhere in view.

Whenever the Great Hall of Spins feature is activated, the meter at the top of the screen is filled by one bar, and as you continue to fill up the bars, you gain access to extra special features.

Once you’ve completely filled the meter up, you get to choose which of the four free spins options to play each time that it’s triggered, and they’re based on famous Norse gods – Valkyrie, Loki, Thor, and Odin.

Option 1 is Valkyrie, the winged female warrior, who offers you ten free games with all wins multiplied by x5 and the ability to retrigger the feature with additional scatter symbols.

Option 2 is Loki, who gives you fifteen free spins and also awards one, two, three or four extra spins when two, three, four or five scatter symbols respectively land on the reel set. Loki’s bonus uses the Wild Magic Feature, and it’s triggered when the special “Wild Magic” symbol appears on Reel 3 where it randomly transforms into extra wild symbols.

Option 3 is Odin, who grants you twenty free spins with his Wild Raven Feature. On any free spin, either one or two ravens can fly onto the screen to turn random symbols into 2x and 3x win multipliers. And, if both ravens land, you can potentially receive a 6x win multiplier.

Option 4 is Thor, and he offers you twenty-five free spins with Rolling Reels. Rolling Reels allows for multiple consecutive wins as symbols that are used to create wins are removed from the screen to allow new ones to replace them. With each consecutive win, the multiplier increases from 2x to 3x to 4x to a maximum of 5x.

If you don’t want to lose your progress in the Great Hall of Spins, make sure that you always play the game at the same online casino or bingo site.

The second bonus feature is called Wildstorm, and it can randomly cause lightning to strike the reel set and turn as many as five reels fully wild.
