The next chapter of the legendary Thunderstruck saga is here. Stormcraft Studios has created another epic online slots game, Thunderstruck: Stormchaser. The series’ original title, Thunderstruck, was released in 2004. This is the fifth installment in the series and the second one from Stormcraft Studios.

If you enjoy Norse mythology-themed slots, then this is one of the best online slots to play. As always, it’s worth checking out online reviews before you play online slots for money, so have a look at this review. 

Game Overview

It’s easy to see why this game is one of the studio’s most popular online casino games to date. It’s filled to the brim with exciting features and bonuses and is visually stunning, too. The game takes place on a 5×4 grid, so you’ll find the symbols displayed across five reels and four rows. It’s jam-packed with a 1,024 ways-to-win mechanic, a Wildstorm free spin with wild reels, a cascade respins feature with multipliers, and a free spins feature — it’s no surprise that players simply love this slot.

The only potential drawback is the return to player percentage (RTP) of 94.01%, which is significantly lower than the industry average. However, given the plethora of winning opportunities and great features, it’s undoubtedly worth playing.

How To Play

As with all jackpot slots, you should pick your wager amount before you play. It typically doesn’t affect your payout whether you pick the minimum or the maximum bet on slots, but you should decide what suits your budget best. In this game, you can choose any bet between $0.20–$25 per spin. 

From here, you have to try and land a winning combination, that is, three or more adjacent matching symbols across a payline. The low-value symbols are the playing cards, while the high-value symbols include a raven, Freya, and Thor, which pay out 3.5x, 4x, and 10x your wager for five in a row, respectively. Thor acts as the game’s wild and will substitute for all standard symbols to help form winning combinations. His hammer acts as the game’s scatter symbol and is the key to triggering the bonus feature.

Cascading reels are active after every winning combination and will be discussed in more detail below. 


The graphics in Thunderstruck: Stormchaser are seriously impressive. Players can tell they’re in for a treat from the very moment the game starts, with thunder and lightning creating an intensely dramatic mood for the opening title. The background to the reels is the city of Asgard, with captivating storm clouds and mountains in the distance.

On the reels, you’ll find gorgeously crafted symbols, including Thor, the God of Thunder, and Freya, the Goddess of Love and Death. There’s also a raven, the Yggdrasil tree, two exterior views of Asgard, and one of the Great Hall. There’s a ton of animation within the slot to look forward to, with the scatter lighting up when it hits a win, Freya descending to take you through to the free spins round, Thor standing on top of the spinning multiplier wheel, and much more. 

Another interesting and unique addition is the option to choose from several different soundtracks available for this game.


Although this is a high-volatility slot, it has some impressive features that make it worth playing. 

Cascading Reels Mechanic

When you form a winning combination, the symbols involved are removed from the reels and replaced with new ones. The new symbols drop down onto the reels, offering an excellent opportunity for further wins. The cascade will only stop once you no longer form a winning combination.

Wildstorm Feature

The Wildstorm feature can be triggered at random during the base game. In this feature, you’ll get one free spin with fully stacked wild reels. This means up to five reels can become stacked wilds. It’s the only way that you’ll get a shot at the 10,000x max win for the base game.

Bonuses and Jackpots

Land three, four, or five scatter symbols (Thor’s hammer) on the reels in the same rolling sequence, and you’re instantly awarded 1x, 5x, or 25x your stake, respectively. You’ll then be taken to a screen where a bonus wheel spins to determine how many free spins you get, as well as your starting win multiplier. Depending on how many scatters you have, you can win the following:

  • Three scatters: 7–12 free spins with a starting multiplier between 1x and 6x.
  • Four scatters: 10–15 free spins with a starting multiplier between 3x and 9x.
  • Five scatters: 15–25 free spins with a starting multiplier between 5x and 12x.

You’ll also be given a random number of Wildstorm tokens from the wheel. These will also be collected every time you land a scatter in the bonus feature. You need to collect 12, 14, or 16 to get 1, 2, or 3 Wildstorm spins after the bonus round ends, respectively.

Land three or more scatters during the bonus feature, and you get five more free spins. And if that weren’t enough, if you manage to land any multiplier symbols at the same time as a win in the bonus feature, the multiplier will be added to the total win.
