Thor’s Lightning Slot


Sharing is caring!

Our rating:
  • Another slot to use the Nordic theme with Gods like Thor and Odin
  • Uses Cluster Pays to provide wins when symbols are clustered together
  • A good few features make the game fun and rewarding

Thor’s Lightning slot certainly gives away what the slot is based on, but it doesn’t give any indication as to how it players. Without going into too much detail just yet, it’s a new slot that uses Cluster pays along with a range of features including free spins to mainly provide high-value symbols or multipliers for bigger wins. There’s a lot to like, so let’s take a closer look.

In terms of the design, Thor’s Lightning slot is pretty impressive. Yes, the graphics aren’t great, but the animations are nice and as you’ll see when you play the game, they do a good job of using some of Thor’s powers or other elements which form part of the features. This is a Cluster pays slot so you must form clusters to get a win using the base symbols. These are as follows, ranked in ascending order based on their value:

  • Blue Symbol (lowest value)
  • Green Symbol
  • Red Symbol
  • Yellow Symbol
  • Bird
  • Wolf
  • Yggdrasil
  • Hammer (highest value)

As base symbols, these will pay out cash rewards when they form a winning cluster. There’s also a Wild symbol which substitutes for all other symbols to help create a win.


Thor’s Lightning Slot Bonuses and Features

Cluster Pays. If you’ve never played a Cluster slot before then don’t worry, they’re pretty easy to understand. Most slots of course have a number of paylines which you use to get a win, but cluster slots instead pay out when you get a number of identical symbols horizontally or vertically adjacent. The is number is five, but can extend up to many more for some bigger wins.

Lightning. Everyone knows Thor can summon lightning so it’s only fitting that it’s used here to help you out. Lightning can be summoned at any time and will remove all low paying symbols or turn random symbols into the same type, or better yet, into Wild symbols.

Hammer. Perhaps the most iconic feature of Thor is his powerful Hammer. It can be used in Thor’s Lightning slot to remove symbol or nudge reels and rows to help generate a win.

Free Spins Bonus. You’ll notice an area in the centre of the reels which you can unlock through winning clusters. Doing so will award you one of the following Free Spins Bonus:

  • Muspell Spins. There are 2 main parts to this Bonus. The first is that during the free spins, you will only have high paying symbols. The second is known as the Lava Feature, which can use lava to destroy symbols, add new symbols or even add Wild symbols.
  • Valhalla Spins. This is a very different type of Bonus as it is played with only Golden Shields. These lock in place and will reveal multipliers for when the Bonus ends, giving you much bigger wins.



Thor’s Lightning slot from Red Tiger Gaming isn’t the first to use the theme of Thor and Norse Gods. It’s been a popular choice for many years and especially now with the release of movies like the Avengers and Thor’s movie itself, of course. This one I like though because it uses a lot of that to make the gameplay fun and interesting. Almost every feature uses things like Thor’s Hammer or Lightning to provide features, and these features are actually pretty impressive. They tend to create more high-value symbols and increase your chance of getting a bigger win, or use multipliers with free spins. Either way, it’s a great, fun slot that uses Cluster pays which I’m quite a fan of so for me, this is a great game that I recommend.
