Thunderstruck II Demo
Here is a demo of the online slot so that you can try it out before spending any real cash on it.
Thunderstruck II RTP and Wagering
The first Thunderstruck game to enter the markets was released back in 2004, almost 20 years ago. Since then, a lot has happened in the gaming scene. Due to this, Microgaming felt the need to update one of its most popular casino slots.
Thunderstruck II was released to enable gameplay from all devices as mobile slots were the new thing. It’s a slot that keeps most basic features from the first game with some exciting updates and great casino bonuses.
Canadians trying the game will be able to win from the 243 paylines that the 5×3 grid offers. To create a winning combination, you’ll have to win from left to right, but only the highest win per way is paid.
Thunderstruck II offers players an RTP of 96.65% with high volatility. This means that it’s very generous in rewarding its players, as a matter of fact, the hit frequency is about 32% so you might win on every third spin.
Lucky players can get a maximum win of 8,000x the stake. The only way to get such a high potential win is through the Wildstorm feature, which is randomly triggered. We will discuss this in more detail below. The bet level ranges from $0.30 to the possible max bet of $75.
Symbols and Audio & Video Design
The graphics of the game are very basic. They have kept the slot very similar to its predecessor, and why shouldn’t they with the success it had? Less is more, as they say. However, the bonus features in the game certainly go for a more is more approach instead.
While enjoying the slot game, Thunderstruck II offers a soothing soundtrack reminiscent of old Viking-movie-soundtracks. As commonly experienced, the music intensifies when you enter the free spins features.
If you manage to get into the free spins bonus features, the colour of the symbols and the grid change depending on which type of Great Hall of spins feature you activate.
In the Thunderstruck II slot machine, you’ll come across a couple of known symbols that make up the game. The low-paying symbols are as follows: 9, 10, J, Q, K and A. Landing 3 or more of these can pay you anything from 0.2x your stake and upwards.
The higher-paying symbols are Viking-themed with Thor being the most valuable symbol. First out is the Viking Longship, then Valhalla, where the gods meet, and you can land wins from it as well as from the gods Loki, Valkyrie, Odin and Thor.
Thunderstruck II also has special symbols featured, the Wild symbol doubles any win it creates and the Scatter symbol (Thor’s Hammer) will take you to the bonus features as well as give you wins.
During the free spins features, you’ll notice an extra symbol, the Wild Magic symbol. We’ll take a closer look at it further down.

The Great Hall of Spins feature has different types of free spins, all adapted to suit the player enjoying them. We’ll take a closer look at all the bonus features immediately.
Free Spin Feature
Most online slots have a bonus game with free spins that all players dream about. Thunderstruck II isn’t any different in that regard, it actually has 4 different types of free spins features.
To get into the bonus games, you’ll have to get 3 or more scatter symbols, Thor’s Hammer. Once you get it, you can get up to 4 options of free spins depending on how many triggers you’ve had. The different options are presented below.
Valkyrie Free Spins
The first option is the Valkyrie free spins, this feature gives you 10 bonus spins along with a 5x win multiplier. All wins during this free spin feature will be multiplied by 5. You may retrigger free spins while in-game as well.
Loki Free Spins
Loki bonus spins become available on the 5th trigger, these are quite lucrative as you get 15 free spins along with the Wild Magic symbols. The Wild Magic symbol appears on the grid on the third row. While there, they randomly turn symbols into wilds. Retriggering spins is still possible here.
Odin Free Spins
From the 10th trigger, you can activate the Odin bonus features. Here, you’ll get a total of 20 free spins along with the Wild Raven feature. The bonus feature activates when Odin’s Raven symbol appears and turns symbols randomly into 2x and 3x win multipliers.
Thor Free Spins
Lastly, is the Thor bonus spin feature. It’s available from the 15th trigger and rewards you 25 free spins and Rolling Reels. The Rolling Reels feature will remove all winning symbols when you land a winning combination, this in turn paves the way for more wins. Subsequent wins increase the win multiplier up 5x, 1 extra per win.
Wildstorm Feature
What’s really exciting about the Thunderstruck II slot machine is that the base game also has an extra feature to make things even more exciting. You don’t even have to enter the bonus rounds to have a chance of landing the max win.
If the Wildstorm feature is activated, you’ll see a grid where 1 to 5 reels will become fully Wild reels. Should you manage to be so lucky to get a full grid with 5 wild reels, you’d win 8,000x your stake.
Jackpot
Unfortunately, this game does not offer any kind of Jackpot. However, the potential 8,000x max win is high compared to other slot games. Keep in mind that you have a chance of winning if you trigger the free spins.
Thunderstruck II Biggest Wins
Thunderstruck II actually offers several ways to win big. As a result of this, we came across many reports of big wins. One player won as much as 1,210x his stake and others won over $40,000. Obviously, the amount won depends on the stake.

Summary
To wrap up our Thunderstruck II slot review, we have to say it left us thoroughly entertained. The game offers a lot of excitement, and it’s easy to see why the original was such a big hit. While the 5 reels and 3 rows may seem simple at first glance, and the graphics could have been a bit sharper, it’s the thrill of the gameplay that truly stands out. The experience of playing Thunderstruck II is what keeps you engaged, and that thrill is hard to match in other slots.
From our experience, big wins are certainly possible, especially if you’re lucky enough to activate the Wildstorm feature or the free spins. While hitting the maximum win of 8,000x your stake might require a bit of patience, the high hit frequency and volatility make sure there’s a steady flow of smaller wins along the way.
In our opinion, Thunderstruck II does an excellent job of keeping the excitement alive, with plenty of bonus features to enjoy. The RTP of 96.65% adds a nice touch, reassuring players that the game offers a fair shot at winning.
With stakes ranging from $0.30 to $75, the game is accessible to all kinds of players, whether you’re just looking to try it out or you’re in for bigger bets. Microgaming has done a great job with Thunderstruck II, and we’d recommend giving it a try. You might just find yourself joining Thor on his adventures and scoring some great wins along the way!
