Thor’s Lightning Slot Machine

Join us for the review of Thor’s Lightning slot as the game takes you on a journey into Norse mythology with a 7×7 game grid, cascading reels, cluster pays, and a new mechanic to trigger the free spins.

Two random features and two types of free spins will keep you on your toes throughout the gaming session, where you could score wins of up to 1,800 times your stake in a single spin.

Norse Mythology Meets Slot Reels

Enter Thor’s Lightning slot to find yourself in the midst of a rugged Nordic winter scene. There's mighty hammer of Thor and rune covered stones surrounding the giant game grid, where more traditional Norse symbols can be found. A heroic soundtrack and utterly dramatic thumps when Thor’s hammer is called to action complete a stunning slot creation.

As usual, Red Tiger Gaming is executing a theme to perfection down to the smallest detail. On this slot game, it extends to the nine regular pay symbols on the reels. At the low end are four smaller rune stones, followed by four Norse battle masks and Thor’s hammer.

The wild symbol substitutes for all symbols. There are no scatters on this game as the free spins are triggered by unlocking the 9-symbol block in the middle of the game grid.

Get Familiar With the Numbers and Stats

The Thor’s Lightning slot machine we are reviewing here is a 7×7 grid game with cascading symbols, drops and cluster pays. A minimum of five adjacent symbols are needed to score a win. Pays for a cluster of 40 symbols range from 5x to 25x your stake. In turn, bet sizes range from 0.20 to 40 coins.

The Return-To-Player rate (RTP) of this medium variance game is set at 96.10%. Thanks to the HTML5 format, you will be able to enjoy playing it on desktop, mobile, and tablet. Too lazy to spin the reels manually? Then use the Autoplay function to set up 10 to 100 consecutive spins with a range of options when the run should stop.

The Cascading Symbols Mechanic

There are different types of reel mechanics that are used to display a spin result on a video slot. As our review team of Thor’s Lightning slot game discovered, the one used on this game is the cascading symbols mechanic.

This slot does not have spinning reels. Instead, symbols drop in a cascade onto the 7×7 grid. A winning combination is removed, and new symbols fall in place. This continues until no new wins occur after a fresh drop. Unlocking the centre section of nine symbols in one sequence will trigger the free spins.

Score More Wins With Thor’s Random Features

Red Tiger Gaming has included two random features in the base game that will help to score more and bigger wins as well as unlocking the Free Spins block. They can be triggered at the start of a new game round and will apply reel modifiers to the current symbol drop.

In Lightning Strike, Thor will summon a lightning strike to remove lower value symbols from the grid, or transform a random number of symbols into one common symbol, including the wild.

Triggering the Hammer Strike will see Thor throwing his mighty hammer onto the reels to nudge or remove symbols and lead to potential new wins.

Enjoy Two Types of Free Spins on Thor’s Lightning Slot

At the centre of the game grid is a locked block of nine symbols which will trigger the Free Spins if it is completely uncovered in a single game round, that can include multiple consecutive cascades. Winning combinations landing adjacent will unlock it progressively. Once triggered, you are asked to choose from two free spins options.

The first is the Valhalla Free Spins, which eliminates the regular pay symbols from the reels and replaces them with blank ones and golden shield symbols. All shields landing on a free spin will be set in place. Once the round has concluded, all shields in view are flipped to reveal a bet multiplier. They will add up, resulting in a total bet multiplier and win for the round.

The second option is the Muspell Free Spins where all low-value icons are eliminated from the reels for the duration of the feature. Spins are played with the same cluster mechanic as in the base game, but two extra features will provide potential to hit winning clusters. A Lava Shower can randomly activate, upon which it will eliminate icons for a free respin. In turn, the Lava Flow feature places identical icons on the reels to guarantee a win.

Other Slots With Cascading Symbols

As mentioned, the mechanic with cascading symbols is not new. It became mainstream after the release of the NetEnt hit slot Gonzo’s Quest. Our review team for Thor’s Lightning slot can also recommend Bonanza from Big Time Gaming.

A Mighty Verdict

Norse mythology is all about the powerful gods, including Odin, Loki, Freya, and Thor. They all have capabilities and skills us normal mortals can only dream of. No wonder that we see so many slots creations featuring one or a combination of the Norse gods.

On Thor’s Lightning slot, the honor goes solely to Thor who will swing his mighty hammer to create big wins of up to 1,800 times the stake. Ready for your encounter with Nordic deities? Play with them here for free or for real money at one of our best casinos.
