Thor's Lightning slot review

Thor’s Lightning bonus features

Rocky, snow-covered crags and glowing runes act as the backdrop to this game, which is also accompanied by a sweeping orchestral soundtrack to add atmosphere.

It’s hard to miss the gigantic game area, with a 7×7 reel structure providing 49 symbol spaces. There are rune stones, which act as low value symbols, and carved stone symbols displaying a raven, a wolf, the Yggdrasil tree and Mjolnir, Thor’s legendary hammer. The latter is the highest value symbol.

This game does not use paylines but awards wins based on clusters. Groups of 5 or more identical symbols mean a win.


The Wild symbol appears as a golden-winged helmet, familiar to those with an interest in Norse mythology. It can replace any other paying symbol.

Lightning Strike and Hammer Strike

There are two random features to look out for in this slot. The Lightning Strike is summoned at random by Thor, whose mighty power then either removes lower value symbols from the reels entirely, making space for new ones, or transforms a selection of symbols into the same symbol, which can even be a Wild.

During the Hammer Strike, Thor will show up and fling his hammer at the reels. This can either nudge a reel or remove the struck symbol, creating the opportunity to land a new winning combo.

Thor’s Lightning Free Spins

At the centre of the game screen, players will see a block of 9 inactive tiles that appear greyed out. When a winning cluster lands adjacent to one of these 9 spaces, it will unlock. When all nine spaces are unlocked, one of two free spins features is activated.

In Muspell Free Spins, the player is taken to a new set of reels with all low value symbols removed. There are two random features that can activate during this round.

The Lava Shower will destroy one or more types of symbols in a burst of flame, triggering a re-spin. Identical symbols are created on adjacent reels in the Lava Flow feature, thus guaranteeing a win.

The second kind of bonus rounds are the Valhalla Free Spins. These take place on a completely empty reel set and only golden shield symbols can appear.

At the end of the free spins, the number of shields will determine the value of the stake multiplier that is calculated on top of the winning amount.

Thor’s Lightning jackpot

The Thor’s Lightning slot does not include a jackpot feature.


Thor’s Lightning has an RTP of 96.08% and a medium variance. This exciting slot will appeal to players who want to prolong their gameplay as much as possible without doing too much damage to their bankroll.

Thor’s Lightning Mobile

Thor’s Lightning is fully mobile compatible and players can enjoy it on iPhone, iPad or Android devices. We do recommend using headphones to enjoy that amazing soundtrack fully.
