Bonus features

Thunderstruck II has a collection of some of the best and most varied bonus features you will find in any slot – one of the main reasons it’s remained popular through the years.

Wilds – The Hammer of Thor will act as a Wild anytime it appears on the reels, substituting all symbols except the Scatter and allowing you to create more winning combinations.

Wildstorms : One of its most lucrative bonus features, the Wildstorm will appear out of nowhere. You will find yourself in the middle of a spin when suddenly the God of Thunder himself makes an appearance on your screen to turn up to 5 reels into Wild reels for one spin. Needless to say, anytime a Wildstorm comes your way you can expect big winnings!

The Great Hall of Spins : Any time you get 3 scatters on any of the reels, you will know the Gods are about to bless you with huge winnings. There are 4 different Free Spins bonuses to choose from, each with its own amount of free spins, multipliers and bonus features. But before you can unlock them all, you must first prove your worth as a warrior to each of the Gods. Every time you enter the Hall of Spins you will level will be unlocked.

Valkyrie Free Spin Bonus : Valkyrie is the first bonus level. The Valkyrie bonus game will award you with 15 free spins, with all of the winnings receiving a massive 5x Multiplier!

Loki Free Spin Bonus : The God of Mischief has many tricks up his sleeves. Loki will provide you with 15 free spins in which he uses his Wild magic to turns random symbols on the reels into additional Wilds for even bigger wins. The Loki Free Spin is unlocked after 5 visits to the Hall of Gods.

Odin Free Spin Bonus : The Allfather of the Gods was famous for using his ravens to see and hear everything he wanted from the world of mortals. In his Free Spin game, he will use these same ravens to award you random multipliers of 2x and 3x and sometimes even 6x on winning combinations on during 20 free spins. You will be worthy of Odin’s magic after 10 visits.

Thor Free Spin Bonus : After 15 entries to the Grand Hall of Spins you will finally be worthy of meeting Thor himself! The God of Thunder will award 25 free spins with rolling reels, which make winning symbols disappear and new symbols tumble down for extra wins. All consecutive wins will receive an increasing multiplier from 2x to 3x, 4x and 5x the amount of your win.




Thunderstruck II has been a smashing success since its release in 2010, and has managed to retain its popularity to this day. While its controls are certainly a bit outdated by today’s standards, the fact remains that it’s quite simply one of the most entertaining slots you will find out there. Its multiple bonus features not only offer players the possibility to win big, but will also keep you entertained for hours while you attempt to unlock all of the increasingly profitable Great Hall of Spins bonus modes.

As a medium volatility slot, you can expect to receive plenty of small and medium wins throughout while you fight your way to the Great Hall of Spins or wait for Thor to make an appearance an unleash a Wildstorm upon you to trigger huge wins.

Overall, if you are looking for cutting edge slots with impressive 3d graphics and slick interphases you may want to look for similar slots like Game of Thrones and The Wishmaster, but if you don’t mind some old school design this game more than makes up for it with its entertainment factor.
