Thunderstruck II

The Nordic Classic

thunderstruck iiIf we were to choose the best online slot ever (the one we play the most), Thunderstruck 2 from Games Global (ex Microgaming) that launched in 2010 would certainly be in the running.

This game has a 5×3 layout and a maximum win of 8000x your stake. It’s a medium high variance game with 243 Ways to Win – you just need to land at least 3 matching symbols on adjacent rows from left to right, or drop in 3 hammer scatters anywhere. The Return to Player on this game is slightly above average at 96.7%.

There was an original Thunderstruck slot which is also very popular, and more often than not, the sequels tend to disappoint. Not so with Thunderstruck 2.

There’s also Thunderstruck Wild Lightning which was developed by Stormcraft Studios in partnership with Microgaming and launched later. This studio followed that game up with another called Stormchaser.

We still prefer the second game.

Thunderstuck 2: The Look

This game has stood the test of time (it launched in 2010) and continues to look the business.

The Norse mythology is great and has been copied many times (but never equalled). We are off to Valhalla to spin with Thor, Odin, Loki and Valkyrie.

Thor’s Hammer is the Scatter that you will need to set off the main event: the Great Hall of Spins, while the Thunderstruck II logo is the Wild that stands in for all the other symbols (except the scatter) and doubles all wins.

There are also Viking Ships, Valhalla and the usual playing card symbols hewn from Norwegian granite.

Pros and Cons

✅ Microgaming’s most popular slot.
✅ Multi-level bonuses to unlock in the free spins.
✅ The random Wildstorm feature is a real adrenaline booster.

❌ The different levels in the bonus take a while to unlock.

Playing the Game

thunderstruck 2Thunderstruck 2 has 5 reels, 3 rows and 243 ways to win.

You will need three or more matching symbols on successive reels, starting from reel 1 to star collecting Norse treasure.

Another cool feature in the base game is a random feature called Wildstorm, which can turn up to 5 reels totally Wild reels for Thor sized wins.

-Thunderstruck II symbol is wild, will substitute and double a win.
-The Wildstorm feature can strike randomly turning up to 5 reels wild.
-3, 4 or 5 hammers gets you in to the Great Hall of Spins.

Multiple entries into the Great Hall will unlock further bonus features.

Great Hall of Spins

Valkyrie is the first bonus you will trigger by landing 3 or more of Thor’s Hammers. This comes with 10 free spins, and all wins are boosted by x5. You can re-trigger more free spins with more scatters.

Once you have entered the Hall of Spins feature 9 times, you will unlock Loki. He comes with 15 free spins with a Wild Magic feature that flips symbols into wilds on the middle reel.

After 10 times in the feature, the Odin is available. You’ll get 20 free spins with the Wild Raven feature. Odin’s birds will flip symbols into 2x to 3x multipliers at random. If you get 2 of these, they will multiply into 6x.

The Thor bonus is the last one to unlock once you have triggered the free spins at least 15 times. You will get 25 free spins with Rolling Reels. Each win increases the multiplier by 1 up to 5x. When you have unlocked all of the gods, it’s down to you which one you pick next time you enter the Hall of Spins. The game engine will remember this number for you, so you can continue playing where you left off last time.

Thunderstruck 2 was one of the first of a series of games in Microgaming’s high quality 243 Ways to Win range.

Later examples include the Gung Pow Slot and the Game of Thrones Video Slot (on this last one you have the choice to play the game with  a set number of Ways to Win, or you can opt for a traditional “Pick your Paylines” game).


What other Thunderstruck Games have been launched?
There was the original Thunderstruck released in 2004, although that is looking pretty dated now. There are 2 sequels to the second game: Wild Lightning and Stormchaser (both from Stormcraft Studios)

How do you get into the Free Spins?
The bonus, called the Great Hall of Spins, is key to achieving a good run on this slot. You will need 3 hammer scatters to get in. You can choose between 4 different bonus rounds. Initially, only the Valkyrie bonus is available, but the other gods will unlock the more times you get into the Great Hall of Spins.
