Thor’s Lightning slot review (Red Tiger)

Thor’s Lightning is a remarkably nice-looking Viking slot by Red Tiger with a few unique features

This has already resulted in many fabulous online slots: Vikings from Netent, Vikings Unleashed by Blueprint Gaming and Vikings Go Wild from Yggdrasil, to name a few.

Red Tiger is known for its frequently innovative bonus features and high production values: their slots not only look good, but they are also very entertaining.

Thor’s Lightning doesn’t disappoint: it looks fantastic and has two sweet free spin bonuses, which you have to unlock with some creative and unusual play.

How does the Thor’s Lightning video slot work?

Thor’s Lightning is played on a 7 x 7 symbol matrix with a breathtaking backdrop of snowy mountains, covered with mysterious rune-stones.

Winning combinations appear in clusters of 5 or more similar symbols. These will disappear, and new symbols will drop into their spaces.

In the middle of the screen, you will find a large block of 3 x 3 symbols. Only by playing and surrounding this area with winning combinations can it be unlocked.

If you succeed, you win 1 of 2 lucrative free spin bonuses.

You are playing with a fixed amount per spin, between $€ 0.10 and $€ 200.

Variance and payout rate of Thor’s Lightning

You can win up to 1,800 x the total bet on Thor’s Lightning, which comes down to medium variance.

The theoretical payment rate is 96.08%. That is an excellent return to player (RTP).

Symbols and payouts

The symbols consist of typical Norwegian mythology concepts: hammers, the Yggdrasil tree (the tree of life), wolves and crows. The low paying symbols are different types of runestones.

The bigger the cluster with the same symbols, the higher the value.

The wild symbol replaces all other symbols.

The highest paying symbol of the game is the golden hammer. If you manage to spin a cluster of 40 or more hammers, you will win 500 x the bet.

The premium symbols award you between 100 x and 200 x the total bet for a cluster of 40+ similar symbols.

A cluster of 30+ identical Stone symbols is worth between 10 x and 25 x the bet.

Mystery features: Hammer

Once in a while, the mighty Thor shows his face and uses his hammer to invoke lightning.

That’s the signal that you’ve won one of the mystery features:

• Extra wilds.
• Low symbols are removed.
• Extra blank spaces on the screen for new opportunities.
• Multiple symbols that change into the same symbol.
• Symbols can be nudged for new payouts.

These mystery features can be handy when you have almost achieved the free spin bonus. Often they will give you that much-needed boost and help you to be more successful in the game.

Free spin bonus

Did you unlock all the squares of the middle 3 x 3 block? Then you win 1 of the 2 free spins bonuses:

Muspell Free Spins: win free spins with extra wilds and mystery symbols. Sometimes symbols will also be removed for additional chances of winning.

Valhalla Free Spins: win respins and spin as many shields as possible for mystery cash prizes.

Both free spins cannot be re-triggered.

Our verdict on the Thor’s Lightning video slot

We are true fans of the Red Tiger slots. This game provider is not afraid to try out new game mechanisms, and the bonus features are almost always unique and quite profitable.

Thor’s Lightning is an excellent video slot: it looks great, doesn’t get boring and has fun bonus features.

In our opinion, the variance could have been a bit higher, but at least you get a lot of playing time for your money.

3.8 out of 5 stars.
