An Introduction to the Thunderstruck Stormchaser Slot
Over the years, Microgaming’s series built on the original Thunderstruck has brought plenty of action-oriented titles like Thunderstruck Wild Lightning. However, this time around, it’s the Thunderstruck Stormchaser video slot that’s the belle of the metaphorical ball. What’s more is that they seemed to have gotten back to the roots of the series while innovating at the same time:

The original Thunderstruck games were known for being some of the titles to first popularize the notion of free spins with multipliers as well as the 243-ways layout.
The gameplay style of this title does include free spins with multipliers. However, they’ve went beyond this by including multipliers in the entire game. What’s more is that the free spins mode is handled in a way that we’ve never seen before. We’ll get more into that further down below. Additionally, players have the “all ways” approach to wins with even more ways to get paid than previous titles in the series.
While all of this is going on, you also have a great presentation with a modern feel. This series of slots has always been based on Thor and other elements of Norse mythology. Accordingly, you’ll find that he’s the centerpiece of the game here. However, the graphical style looks like something out of a popular Marvel film. To this end, we have to say that the background and symbol set are more detailed than probably any other slot we’ve seen in a long time.
Betting and Layout
Microgaming put this title together in a way that lends itself to a tremendous amount of action. Starting with a high hit-rate and plenty of visual real estate for features is a good approach in titles like this. In what follows, we’ll show you what you need to know and how the betting and wins operate:
- The grid used in this game has five vertical reels paired up with four horizontal rows. This makes it slightly larger than the usual video slot format.
- Instead of paylines, games in this series are known for using the “all ways” approach. Subsequently, you have 1,024 ways to win in this title.
- Payouts are awarded for matching symbols on consecutive reels starting from the left and working toward the right. However, where those symbols fall on those reels doesn’t actually matter.
- On the lower end of the scale, the minimum bet size available for this game is €0.20 per turn. That’s plenty low enough for pretty much everyone who might want to play.
- Microgaming also allowed for bet sizes that run up to the €25 level.
- Additionally, the betting interface allows for a few “quick bet” sizes that make it easy to jump straight to what they’ve predicted are the most common sizes that players prefer.
Other Information
In most games with so many ways to win, you’re looking at a volatility on the lower end of things. However, here things are a bit different. Microgaming set the feature set up in a way that the volatility is actually a bit above-average. We place it somewhere between the medium and medium-high distinctions as we use them, but the point is the same no matter how you describe it. Your swings will be greater than you may expect going into this title, and we’ll get into why below.
We also want to point out how wins are broken down. Even though no currency markers are used in the pay table, those wins are actually the exact currency amounts that you stand to win based on your current bet size. Accordingly, increasing and decreasing your wager will change those values proportionately. However, to make things clear to players no matter how much they bet, we take a different approach here. We list wins below as a multiple of your overall bet size. This makes it clear what the wins look like no matter what your actual wager size happens to be.
Gameplay and Features for the Thunderstruck Stormchaser Video Slot
In other Norse mythology slots like Gates of Valhalla, we see a lot of emphasis put on tie-ins with the theme. This is the case in the Thunderstruck Stormchaser online slot as well. In fact, everything ties in perfectly not only with the theme itself but with the more modern style used to present that theme. Additionally, we love how these elements come together to provide players with a super cohesive experience.

Wild Thor Symbols
The very first mechanic we want to address is the wild symbol. It’s Thor, which makes sense considering the ongoing theme of the Thunderstruck slot series. Additionally, the wilds are critical in “all ways” style games because of how much easier it is for them to help with creating a new winning combination compared to more traditional payline-based structures.
Along these lines, the wilds can be found on all of the five reels. This means you get payouts for combinations of only wild symbols as follows:
- Five of a Kind – 10x
- Four of a Kind – 2.5x
- Three of a Kind – 0.75x
You’ll find that the wilds substitute for everything with two exceptions. They don’t substitute for the scattered hammers, and they also do not substitute for the multiplier symbols.
Rolling Reels Mechanic
The Rolling Reels game mechanic is what other providers might call an avalanche or tumble feature. In any case, the idea is pretty straightforward. Each winning combination pays out before its respective symbols are removed from the game board. From there, new symbols “roll” down into place until the board is filled again, and you get a new chance to pick up additional payouts.
Microgaming has set this title up in a way that you have no limit to the number of Rolling Reels activations that can come as the result of a single regular spin.
Scattered Hammer Payouts
Since the Thunderstruck Stormchaser video slot centers around Thor, it makes sense that his hammer is the scatter symbol. We have to admit that it’s a cool-looking symbol. Additionally, it offers the following payouts:
- Five of a Kind – 25x
- Four of a Kind – 5x
- Three of a Kind – 1x
You need to know two things about this symbol. First, it offers the best individual win available in the game. Second, it pays no matter which reels or positions it lands in.
Wildstorm Feature
The Wildstorm is a random feature that can trigger at any time in the regular game mode. It offers a single free spin, but a “wildstorm” happens that adds wilds to the board. Up to five symbols on the spin can be converted into wilds. Since you have 1,024 ways to win, and since the wilds offer some good payouts and can land anywhere on the grid, you can see how this is a value-packed game mechanic.
Multiplier Symbols
Random multiplier symbols can land on the board. When they do, they multiply your wins by the given amount. That’s really all there is to them. Microgaming apparently just wanted an excuse to give players bigger wins than usual, which we can get behind.
These multipliers can range from 2x up to the 20x level.

Thunderstruck Stormchaser Free Spins
Three or more scattered hammers takes you to the free spins bonus round. You essentially have a random number of free spins and starting multipliers. However, the pool of random possibilities these are chosen from increases with the number of scatters you use to trigger the feature.
During the free spins mode, the Wildstorm mechanic will trigger much more often. This makes the free spins worth more than their regular counterparts.
How to Win at Thunderstruck Stormchaser
Players are given two primary ways to enjoy this title. The first is the straightforward way with the normal game mode. In this mode, the volatility is slightly above-average due to the feature set. With higher swings than usual, some players may want to lower their bet size slightly to compensate.
However, the second option is to simply purchase the free spins. To do so costs 50 times your starting wager, so lowering your base bet size is probably a good idea. Nonetheless, you’ll force the game to give you at least three scatters. To be clear, it is possible to get four or five this way, but a minimum of three are guaranteed.

Payout Structure for the Thunderstruck Stormchaser Online Slot
The woman who appears to be Hela with purple hair is the best-paying regular symbol. He awards 4x for five of a kind. Just after this is the pair of black crows, which earns 3.5x for five of a kind combinations. Five of the throne and five of the city of Asgard pay 2.5x and 2x, respectively. Subsequently, you can earn wins of 1.75x and 1.5x for five of the tree or tower symbols.
Microgaming put the card rank symbols on rune-like stone tablets. This fits the theme perfectly and also looks great. It starts with the A and K runes, which both pay 1.25x. From there, the rest of the pay table is filled out with the Q, J, 10 and 9, which all pay the same 1x prize for five.
Overview
Unlike titles with similar themes like Tales of Asgard Freyas Wedding, the Thunderstruck Stormchaser slot is a part of a series of games that go back well over a decade. They’re generally considered to be Microgaming’s original major series of slots, and the early editions in the Thunderstruck slot series influenced the entire video slot industry in ways that are still felt today.
However, they were still able to keep things modern in this title. From the theme to the gameplay, it’s all gorgeous and action-packed.
