Thunderstruck II Slot Review

Thunderstruck II is a video slot brought to you by Microgaming. The game was launched in May 2010 and has become of the most played slot games online today. It features 5 reels and 243 ways to win (paylines) and you can play up to 300 coins at once (up to £15 a spin). It has a Norse mythology theme which means it’s based on Nordic gods such as Valkyrie, Loki, Odin and Thor.

Thunderstruck II has a small 1,000 coin jackpot though which is disappointing. Apart from this, you’re in for a real treat. Look out for the Thunderstruck II logo as this is the Wild symbol and substitutes all symbols except for Thor’s Hammer symbol. The wild symbol won’t apply during the Wildstorm feature – this is a feature that is triggered randomly. This feature will earn you 1 free spin with up to 5 reels turning wild. If you get 4 or more wild reels, prepare yourself for a huge win.

The main feature of Thunderstruck II is The Great Hall of Spins feature – this consists of free spins with a multi-level element. To gain access to the feature, you need to get 3 or more Bonus Hammer symbols. You will notice there are 4 levels to the bonus feature which you can trigger by getting into the bonus round a certain amount of times.

First up is the Valkyrie feature which is triggered on your first to fourth feature triggers. You are rewarded with 10 free spins with all wins multiplied by 5 (5x multiplier). The good thing is that you can retrigger more free spins if you’re lucky.

Then you have the Loki feature which is available from the fifth to ninth feature triggers. You are awarded 15 free spins with the Wild Magic feature. The Wild Magic symbols on the middle reel transform symbols into additional wilds.

The Odin feature is playable on the tenth to fourteen feature triggers. You will get 20 free spins as well as the Wild Raven feature. Odin’s Raven symbols can randomly turn symbols into 2x or 3x multipliers. Get 2 and you will benefit from a 6x multiplier.

Finally you have the Thor feature which is available from the fifteen feature trigger onwards. Here you receive 25 free spins with Rolling Reels. Consecutive winning spins increase the multiplier from 2x to 3x to 4x to 5x. This means you can potentially getting a 5x multiplier on every single free spin.

Once you trigger all 4 levels, you can choose whichever level you fancy once you go back to the Great Hall of Spins feature. The game has a memory meaning you can pick up where you left off (there’s a bar measuring your progress). Even though this is a medium variance slot, it’s well balanced and can produce some huge wins. I really like the Thor feature as Rolling Reels can give you a huge return – it’s no coincidence the Rolling Reels feature is found is other Microgaming slots such as the higher variance Immortal Romance and blockbuster Avalon II.
