Thunderstruck II Game and Bonus Features

Here’s where we’ll cover all the exciting features of Thunderstruck II.

BONUS GAMES FEATURES2Rolling Reels, Multipliers 

Great bonus features to play with

Thunderstruck II has no shortage of bonus features. You have wild symbols (which all double your wins), and scatter symbols. There are several different “modes” of free spins you can activate with additional features like rolling reels and multipliers. 

The max payout is 8,000x your wager which is sizable. The RTP is well above average at 96.65%. With medium volatility, Thunderstruck II should also payout somewhat consistently. 

The symbols

Interestingly, the top-paying symbols in Thunderstruck II are the wild and scatter icons. Usually, these symbols don’t payout. The other main symbols are Thor, Odin, Valkyrie, Loki, a golden city, and a ship. The low-paying symbols are the royals, A, K, Q, J, 10, and 9. 

The wild symbol is the Thunderstruck II logo. Besides substituting for paying symbols, all wins it’s a part of will be doubled. The scatter symbol is Thor’s hammer. With three scatters, you can unlock the free spins round.

Special events that can occur during the base game

Free spins are the main thing to look out for in the base game. By getting three scatter symbols, you can trigger one of four different free spins options. 


The Valkyrie is the first mode you’ll unlock, and it comes with 10 free spins with a 5x multiplier. 


The Loki Free Spins mode requires five triggers to be activated. You’ll receive 15 free spins, and the wild magic symbol can appear randomly on reel three. When this appears, up to 15 symbols can be transformed. 


Getting Odin will take a bit more effort as you need 10 free spin triggers. When you activate this, you’ll be awarded 20 free spins and the wild raven feature. The ravens can transform up to two symbols into wilds with a 2x or 3x multiplier. If two symbols are transformed, you get a 6x multiplier on your win. 


Thor free spins are the hardest to unlock, requiring 15 triggers. This comes with 25 free spins and rolling reels. With rolling reels, you can get several wins in a row, and each one comes with an additional multiplier.

Like many slots, Thunderstruck II comes with an autoplay option. There’s no loss limit, though, but you can stop the spins at any time. Alternatively, you can also turn on turbo mode by clicking on the lightning bolt icon. This makes the action go a bit faster

You can adjust your wager from $0.30 up to $60. With a reasonably wide betting range, it makes Thunderstruck II appealing to players of all levels. Finally, the icons aren’t all static but rather become animated when you win. 

Thunderstruck II’s Theme

Thunderstruck II borrows heavily from Norse and Germanic mythology. The main symbols, Odin, Thor, and Loki, are all gods. The most well-known out of the three is Thor, largely thanks to several blockbuster films. Thor’s hammer is the scatter symbol, and you’ll also find other nordic imagery among the symbols, such as the Viking ship.

Dated but decent graphics

Considering Thunderstruck II is quite old at this point, the graphics are still fairly decent. The symbols are all detailed and sharp. However, the slight facelift from Microgaming doesn’t do much to hide the fact this is still a pretty old game. For example, the background is just a plain stone wall. You won’t see rich background details like those found in modern slots.  

Basic soundtrack

There’s not a lot of sound in Thunderstruck II. You won’t hear any kind of music playing in the background throughout the game. Instead, there are only some basic sound effects when you spin the reels. 

Thunderstruck II Developer

Microgaming, the maker of Thunderstruck II, is no stranger to the world of slots. The developer has released well over 800 slots to date and is a major fan favourite. In addition to slots, they also produce table games for online casinos. 

Conclusion – Is Thunderstruck II Worth Playing?

The original Thunderstruck was incredibly popular among slot fans, eventually leading to the release of Thunderstruck II. Even today, the slot is still widely enjoyed by many players, and the above-average RTP and sharp symbols have contributed to lasting success. 

However, there are several factors that show Thunderstruck II is definitely an older game. The background is very plain, and there’s no music or soundtrack. 

From a numbers perspective, Thunderstruck II is still worth playing, but if you’re looking for a bit more excitement and visual dynamics in your slot, this one may fail to deliver.
