Thunderstruck II Slot Game in Detail

Thanks to the 2020 update, Thunderstruck II pokie has significantly improved its graphics and gameplay although there is still room for perfection. Thanks to the sounds and good-looking images of the Norse gods, you can get an immersive experience from the very first moment.

Thunderstruck II, one of the best online slots at the moment, has 5 reels and 243 paylines across 3 rows. To get a winning combination, players should land 3,4, or 5 matching symbols in the base game. The bet range is rather favorable – between 1 and 10 coins or between $0.4 and $20. This makes the slot a great option both for risky punters and beginners. And if you are not ready to bet real money, play Thunderstruck II slot for free at Casino HEX.

How To Play Thunderstruck II Slot Machine

As you know, Thunderstruck II by Microgaming was launched over a decade ago and the layout may seem a bit outdated. Thus, it may be hard to understand the rules, especially if you are a beginner. That is why you might need an instruction on how to play this casino game:

  1. Press the Gear icon on the left. There, you can turn the sound on or off, select the quick spin feature, and alter other settings.
  2. Choose ‘?’ to read a detailed description of the game rules, bonus features, and symbols.
  3. Alter +/- to set the necessary coin size. When choosing Bet Max, you automatically wager the maximum sum.
  4. Press the Spin button to start the reels and follow the action on the screen without a need to do anything.

Don’t forget that like any other online video slot, Thunderstruck II is automatic, so you don’t need to participate. Just choose the coin size and start spinning the reels.

Thunderstruck II Game Features Explained

One of the things that we love about this game is that it is filled with a variety of bonuses. There are random wilds, four free spins rounds, rolling reels, multipliers, and much more. If you are a fan of action and want to play a dynamic casino game, Thunderstruck II bonus features will surely cover your needs. Below, we are going to tell more about the Great Hall of Spins and the Wildstorm feature.

The Great Hall of Spins feature

Thunderstruck II slot is mostly known for its free spins feature and without it, the game would surely lose its charm. To access the Great Hall of Spins, a player needs to collect 3, 4, or 5 Thor’s Hammers which is the Scatter symbol. See these hammers on the reels? Then you win 2, 20, or 200 of the total bet. When triggering the Thunderstruck II free spins feature several times, you get access to four various bonuses. There is a progress bar where you can see how many times you have triggered it. The available features are:


This free spins game is rewarded to players who trigger the Great Hall of Spins once. It rewards them with 10 FS and a 5x multiplier. The Valkyrie bonus can be retriggered multiple times, so the maximum bonus is 20 FS and a 1,383x win.


If you trigger the bonus at least five times, the Loki Free Spins feature is activated. It gives players 15 free spins and adds the Wild Magic feature. When they land on the third reel, the symbols randomly turn into extra Wilds. With the help of the Loki bonus and Wild Magic symbols, users can win additional free spins. The maximum reward during this round is x 8,000 of the initial stake.


This bonus is available from the tenth trigger and rewards players with 20 free spins on Thunderstruck II. It also activates the Wild Raven feature – they randomly turn symbols on the reels into 2x and 3x multipliers. If both of the wild ravens appear, you’ll multiply the winnings by 6. In total, the win per spin equals x3,320.


The most rewarding and rare free spins feature is available to those who trigger the Great Hall of Spins at least 15 times. The Rolling Reels feature activates 25 bonus spins and the combination doubles the winnings. The following wins boost the multiplier and it reaches x3, 4, or even 5. The maximum win is x 1,383 per free spin.

Wildstorm Feature

Thunderstruck II online slot wouldn’t be itself without this engaging and unexpected bonus. Wildstorm is a randomly triggered feature, so there is no way you can predict it coming. When this feature is activated, you will see Thor and lighting bolts that turn up to five reels into the Wild ones. The lucky players who get all Wild reels, multiple the total bet by 8,000!

Scandinavian Folklore and Norse Gods in Action

Thunderstruck II casino slot has a distinguishing theme that sets it aside from other pokies. If you are a fan of Norse mythology or at least Marvel comics with Thor and Loki, you’ll be thrilled! Especially now, when the game has undergone several massive improvements.

When joining the machine, players are greeted with such Nordic gods as Odin, Thor, Valkyrie, and Loki. Other symbols that remind us of the main theme are Thor’s Hammer, Viking Longship, Thunderstruck II logo, and Valhalla. Symbols of the lowest value are cards: 9 through Ace which is a bit weird to see in a mythology-themed pokie.

Here’s how game symbols pay out when collecting 3,4, or 5 of them:

Game Symbol 3 Symbols 4 Symbols 5 Symbols
Valhalla x0.5 x1.66 x10
Viking Longship x0.5 x1.66 x8.33
Wild x2.5 x6.66 x33.33
Scatter x1.2 x20 x200
Loki x0.66 x2.66 x13.33
Valkyrie x0.66 x2.66 x11.66
Thor x1 x3.33 x16.66
Odin x1 x3.33 x15

Thunderstruck II RTP Rate & Game Volatility

Our review of the Thunderstruck II slot machine would be incomplete without discussing its return to player rate and volatility. This rate shows how much money you can potentially get back on every dollar spent. The higher the indicator is, the better. Thunderstruck II has an impressive 96.65% RTP which means that the game’s payout is quite good and the house edge is only 3.35%.

But keep in mind that it is a high volatility slot which means that the machine pays out higher sums but less frequently. Thus, Thunderstruck II might not be the best option for players with a limited budget or those who follow the ‘slowly but surely’ motto.
