With superheroes, monsters, and ancient legends so popular in film and TV at the moment, it was almost inevitable that we would see the influence of these pop culture fixtures in online slots games. Thunderstruck is a game that proves that myth and legend will always be popular, as it gives players the thrill of spinning the reels in a fantastic ancient Norse theme.

Visuals and Presentation

Even those who aren’t familiar with Norse mythology will know a certain character named Thor. This otherworldly god uses his lighting hammer to dish out justice as he protects the universe from those that would do it harm. Legend has been used to great effect in Thunderstruck, inspiring the developers to create big, bold, in-your-face style graphics.

Players will find icons based off of Thor’s Hammer, supernatural lightning, and of course the image of Thor himself. Even the regular symbols have received the legendary treatment. They’re big and bright, and set against a backdrop of ominous cloud and lightning.

Not all of the sounds used in the game are unique to the theme, but they still offer a decent level of immersion. Sounds keep things exciting when reels are spun, lines are matched, and payouts claimed.

Thunderstruck is not the newest slots game, but it is still one of the most popular. This is no doubt largely attributed to the popular theme and the exciting visuals.


Gameplay will feel familiar to regular slots players, and is simple to learn for newcomers. There’s not a huge amount of variation that can be added to online slots without detracting from the basic formula, so it’s good to see that developer Microgaming hasn’t deviated too far from familiar paths.

The game is aimed at low rollers, which helps to make playtimes longer, and also appeals to beginners. Bets range from 0.01 to 1.00, and the maximum bet is limited to 45 coins. There are only 9 paylines to choose from, which means that betting in the game is simple and quick.

Wild and Scatter symbols feature in the game, and both affect gameplay as expected. The Wild symbol is Thor, and it can be used to make up winning combinations with other symbols. It also adds a 2x multiplier when it is used to create a winning line.

The Scatter symbol is represented by a Ram. Scatter symbols can appear anywhere on the reels, and when players have three or more they will enter in to the bonus game mode.

Jackpots and Bonuses

Basic gameplay makes the game accessible, but it’s the bonus features that will keep players interested in the game.

When three Scatter symbols are revealed the player will enter the free spins bonus game. In this mode there are 15 spins available. The great thing about free spins in Thunderstruck is that the mode can be retriggered if three Scatter symbols are revealed on a free spin.

Players also have the option to gamble on their wins. The gamble feature presents a simple guessing game where players guess red or black on a random card draw. This gives a 50/50 chance of doubling the win. Players that are feeling adventurous can guess the suit of the card that will be revealed, which provides the chance to quadruple any winnings.

The maximum fixed jackpot can be won by lining up five Thor symbols, and the value is a staggering 10,000 coins. The secondary jackpot is a more modest 2000 coins.

What’s Hot

The theme is the highlight in this game, and it’s important not to underestimate how a well-designed game can improve the slots experience. The large jackpot and simple but exciting gameplay round off the experience.

What’s Not

There’s no progressive jackpot, and the secondary bonus is relatively low. High rollers may be disappointed in the low maximum bet.

Final Thoughts

It’s clear why Thunderstruck is such a popular online slots game. The graphics are bold and exciting, without detracting from gameplay, the game is smooth thanks to Microgaming’s software, and the bonus features and large jackpot increase appeal. Slots players new and old will love the longevity to be found in this low stakes game. A 10,000 coin jackpot in such a good looking game makes it likely that Thunderstruck will remain an online casino staple for years to come.
