The pantheon of Norse gods is a great source of inspiration for slot game developers. The developers at Red Tiger Gaming have come with the idea to make the chief god and god of thunder in Norse mythology the subject of this rather epic game. The reels cascade rather than spin into place. This slot has no pay lines and you create a win when you play at least 5 adjacent symbols in one round. When you click ‘play’ to start the next round the winning symbols disappear and are replaced with new ones that cascade into place. This feature continues until you no longer play a winning cluster. When you manage to fill the entire grid with winning symbols, you are awarded from x5 up to x25 your stake. If you manage to charm the god of the realm and all is perfectly aligned, you can make wins of no less than 1,8000 your bet.

Special Features

Thor’s Lightning has few special features that are quite original. The game doesn’t have any Scatters and the Free Spins Bonus game is triggered by unlocking the centre grid. Thor’s Hammer can provide some extra action and chances to create more wins.

Wild Symbol

This standard slot game feature also appears in Thor’s Lightning slot and fulfils it usual symbol substituting function.

Free Spins Bonus Round

You are awarded free spins in the Bonus round, which you trigger by unlocking the centre grid. You can do this by creating winning clusters that touch the edges of the locked grid. When this happens, the outer tiles will become electrified and crack to reveal the Thor’s Lightning Bonus feature. You can then select one of two realms for the Bonus Game to take place: either in Valhalla or Muspell realms.

Valhalla Free Spins

In this Free Spins mode regular symbols are removed and replaced with blanks and symbols of golden shields. The shields are locked in place and once the Free Spins mode has come to an end, they each will reveal a multiplier. These multipliers will be added together to give you a total multiplier on top of the wins you have made in this mode.

Muspell Free Spins

In this mode all low-value symbols are removed and you can benefit from two added features to increase your chance of hitting winning clusters. The Lava Shower can be triggered at random and removes one or more symbols for a re-spin. The Lava Flow feature creates matching symbols on adjacent reels, so you are guaranteed a win.

Thor’s Hammer and Lightning Strikes

Of course, the chief god himself needs to play a role in the game named after him and he makes his appearance when two different features are triggered. When the Lightning Strike feature hits, Thor summons a lightning bolt to remove lower value symbols from the reels or it turns a random number of symbols into the same symbol, which can be a Wild. When the Hammer Strike is activated Thor throws his hammer onto the reels and symbols are removed or pushed into a different position to give you the potential to create a new win.


In terms of theme, this slot is a must play for lovers of Norse mythology especially if you like the darker and grittier side of this lore. Thor’s Lightning is well designed and has original features like the 7×7 grid structure, the unlocking of the Free Spins round and the Hammer and Lightning features.

The game has a high win potential, but, as often is the case, it is not easy to hit those bigger wins. As Thor’s Lightning is a medium variance slot, smaller players should be able to make some decent wins with a bit of luck and patience.
