thunderstruck 2 slot

The Thunderstruck 2 slot remains one of Microgaming’s most popular titles with great gameplay, entertaining graphics and a wonderful soundtrack.

It remains the slot that many others are bench-marked against.

The Facts

thunderstruck 2 scatter symbol

Thunderstruck 2 is a five-reel and three-row online slot game with 243 Ways to Win from Games Global (ex Microgaming).

This is a medium to high-variance game, and one of the most popular slots of all time. It’s themed on the Norse legends and has a multi-level free spins bonus which you unlock on multiple visits.

The maximum win is 8000x on Thunderstruck 2 and it carries an RTP of 96.65%. Features include Avalanche Wins, Expanding Symbols, Free Spins, Multipliers, Scatters, Wilds and a Multilevel Bonus. Thunderstruck 2 was launched in May 2010.

Thunderstruck 2 Slot: the Low Down

thunderstruck 2 wild magic slot

The Thunderstruck 2 Slot is probably the most famous Microgaming video slot available today, besides perhaps Immortal Romance (which runs off the same game engine). It owes its success to its gameplay. This is a slot that will entertain you, we are confident of that.

If you like Nordic-legend-themed slots, there is also a great one built by IGT called the Nordic Heroes slot- it´s pretty complicated, but also very good.

There is also the original Thunderstruck game (looking a bit dated) and two sequels called “Wild Lightning” and “Stormchaser” that were launched in partnership with Stormcraft Studios.

Our favourite is still the second game though.

The Low Down

thunderstruck 2

This is a video slot with 243 Ways to Win. Others in this category from Games Global include the Game of Thrones Slot.

There are wilds, a Wild Storm feature (triggered randomly) and a multi-level free spins bonus round.

Look out for Valkyrie, Loki, Odin, Raven and Thor. There’s also the Mjölnir (Thor’s hammer – the scatter), longships, a rainbow road and 9, 10, Jack, Queen, King and Ace icons.

Can you guess our favourite bit? When two hammer scatters drop in, the music ramps up while you hope for a third. “Thud!” If you land three hammers, you are into the free spins bonus also known as the “Great Hall of Spins”.

Mesmerising, Norse music drifts over you as you play. When something big hits, the volume gears up and your heart starts beating a little bit faster. The sound effects, HD graphics and animations make this slot one of the prettiest and engaging games we’ve played. They have done a great job on it.

Pros and Cons

  • Four levels in the Bonus Feature keep things interesting
  • The random Wild Magic feature can be lucrative if you are lucky
  • The graphics and sound are still great – they have aged well.
  • It can take time to unlock all of the bonus features.

243 is the Magic Number

The Thunderstruck II slot is part of Microgaming’s 243 Ways to Win range (other examples include Immortal Romance and the Playboy Slot Machine). You can bet from £/$/€0.30 to £/$/€15 per spin. You can’t change the number of active pay lines (it’s not that kind of slot), but you can change your bet level of course.

As long as you land matching symbols on adjacent reels from left to right, you will trigger a win.
Hit the “Expert” button if you want to use the auto spin function, or just stick with the basic control panel: it’s up to you.

The Thunderstruck 2 Slot Logo is Wild

The Thunderstruck II logo is wild and will stand in for all other symbols except for the hammer scatter. Any win made with a wild is doubled during the base games and free spins.

You can get hit by a Wild Magic (Wild Storm) bonus which is triggered randomly and is very exciting. This can fill up to all five reels with wilds which can mean big wins!

Free Spins in the Great Hall of Valhalla


Land three or more Hammers (Mjölnirs) to get into the Great Hall of Spins. The more times you get into the Great Hall, the bigger the number of options you will get.
For example, the Valkyrie bonus gets you ten spins with a 5x multiplier from 1 to 4 visits.

After the fifth visit, you will get 15 free Loki-themed spins with the possibility of magic wilds on the third reel.

After the 10th spin, along will come Odin with 20 free spins with wild ravens, which can change icons at random to net you wins. Any wins are multiplied by six if two ravens come into play.

The ultimate? After 15 visits to the Great Hall, you will get access to Thor Spins. This means 25 free spins and consecutive wins increase the multiplier to a maximum of 5x (Avalanche Wins).

You can also trigger more consecutive wins with rolling reels. 

Thunderstruck II: A Hot Slot

The Thunderstruck 2 Slot is a hot game and one of Microgaming’s classics along with Immortal Romance! One of the best games from Games Global (ex Microgaming) since the Tomb Raider slot series and one that has aged well.

Question and Answers

  • Why are there four Free Spins options in Thunderstruck 2?
    Each of the four Norse gods (Odin, Loki, Valykrie and Thor) is in charge of a bonus. When you first get into the Great Hall of Spins, only the Valkyrie option is available, but as you unlock the other gods with multiple entries into the bonus, the more options you will have.
  • What is the maximum win?
    You can win up to 8000 times your stake.
  • How does the 243 Ways to Win mechanic work?
    There are no set pay-lines. You make wins by lining up three or more symbols on adjacent reels from left to right. So if you can see a Thor on reel 1, 2, 3, 4 and 5 when the spinning stops, then that is a 5 Thor win which pays out 16.7x your stake.
  • How do you get into the free spins?
    You will need three Thor hammer scatters anywhere across the reels to trigger the free spins. These drop in with a resounding thud. So, let’s say you can see a Mjölnir (Thor’s hammer) on reels 1,3 and 4 when the reels stop spinning. Then you enter into the Great Hall of Spins where you will choose your free spins bonus.
  • What is the RTP of Thunderstruck 2?
    The Return to Player on this game is 96.65%, which is above average.
  • What other Thunderstruck games can you play?
    As well as this sequel, there is the original game, although the design is looking pretty dated. If you are looking for a classic, this is it however! You might also like Thunderstruck Stormchaser and Thunderstruck Wild Lightning: both sequels were designed by Stormcraft Studios in partnership with Games Global.
