Gameplay & Bonus Features


In Thunderstruck 2 slot, you will encounter the most famous of the Nordic gods, like Odin, Thor and Loki and they will represent  high value symbols of this game. Of course Valkyries will aid you during your play sessions as well.

Low-paying icons are portrayed by the default playing card symbols, from 10 to A. Although they are designed in a way to match the theme of the game.

Winning combinations start from landing at least 3 of the same symbol on the winning payline, starting from the left reel and you will get the most earnings from the combination of 5+. The Thor symbol will pay you out 500x your bet for 5-of-a-kind, which is the most among the regular symbols.

The Thunderstruck II game logo takes the role of the Wild, it can substitute for any other regular symbol sans Scatters and increases the chances of forming winning combinations, plus you  will get double of your winnings from them.


The Great Hall of Spins

There is also the Scatter Symbol in this slot and it is represented by the Hammer of Thor icon. The brave heroes who manage to land 3 or more Scatters with the single spin will unlock a Free Spins Mode called Hall of Spins where the challenge will await you. The Gods of Asgard will also award you with 1, 2, 20 or 200x for getting either 3, 4 or 5 Thor Hammers.

Free Spins Mode in Thunderstruck 2 features 4 separate stages. When you get to the Hall of Spins for the first time, only one will be available for you but as you continue to trigger the feature, more stages will be unlocked. And don’t worry, the progress will be saved, so you can continue your journey between separate play sessions.

Each of the stages will award you with a different amount of Free Spins and will have its own interesting feature that makes it special.

In the first room of the Hall of Spins, a Valkyrie will be waiting for your arrival. Your bravery will be awarded with 10 Free Spins with 5x multiplier on wins. You also can retrigger the Feature and gain additional 20 Bonus Spins maximum.

As you activate this mode for the 5th time, Loki will offer you a tricky challenge. Right at the beginning you will get 15 Free Spins with a Wild Magic Feature. Wild Magic Symbol lands on the reel 3 and has the capability of replacing other symbols with Wilds. During this mode, you can gain 1, 2, 3 or 4 of Extra Spins if you get 2, 3, 4 or 5 more Scatters.

After you pay a visit to the Hall of Spins for the 10th time, Odin will come out to greet you with a 20 Free Spins and a Wild Raven Bonus Feature as a bonus. Raven companions can replace any symbols with either 2x or 3x multipliers. If you manage to get both Raven Symbols to land at the same time, your wins will be subject to a 6x multiplier.

The last level of the Hall of Spins features Thor, the God of Thunder. You will gain access to it after entering the Feature for the 15th time. Right as you enter, you will be given 25 Spins together with the Rolling Reels Bonus. With this bonus, each of your consecutive wins will increase the multiplier from 1x and up to 5x.

After you unlock all the levels, it’s up to you which one you want to choose the next time around.


Another feature in Thunderstruck 2 is the Wildstorm feature that can trigger randomly during your playing session. You will notice it when the music will change to an ominous track and a lighting bolt will strike from the sky and 1-5 reels will be converted into the Wilds. If luck is on your side and you get a 5-reels transformed into Wild Symbols, you will win the main jackpot worth a whole 2,400,000 coins.
