Listening to the storm

There’s no doubt about it – Thunderstruck II is very well-themed, and the graphics play a huge part in this. The part-historical, part-mythical feel of this slot is exacerbated by the detailed depictions of various Norse gods, and of course Thor’s hammer too. The low-value symbols are all carved from stone and look like ancient artefacts – the colour scheme is mostly blue and grey.

The background is a sky full of dark clouds – of course, Thor is the god of thunder, so it’s no surprise that his slot would look so foreboding. This game might not be all sunshine and rainbows, but the dull, gloomy atmosphere really works. And what of the music? You might be expecting weather-based sound effects to be prevalent here, but the main sound is an unsettling musical number – it increases in intensity when you get a win on the board, so watch out for that!

More ways than the gods

Instead of having the usual 20 or 40 paylines, Thunderstruck II does things differently. Although it’s not quite Megaways, the offer of having 243 potential ways to win is definitely an exciting draw. To win, you just need to match symbols from left to right across the reels – adjacent symbol combinations will always pay, so there’s no need to remember the paylines! Watch out for the Wildstorm Feature too. It can strike randomly, and turn up to five reels into wilds – however, free spins won’t be triggered here.

With five reels, there are 15 symbols on the play board at any one time. The wild symbol substitutes for all other symbols apart from the scatter symbol, and when appearing as a substitute in a combination will double your win. It also pays out itself, and is twice as valuable as the highest-paying normal symbol – Thor himself. Of the regular symbols, the gods pay the best, and then before we get into the letters and numbers there’s a castle and a ship too. Scatter wins are multiplied by the total bet staked, and are awarded no matter where they are on the play board.

Entering The Great Hall

Do you feel up to entering The Great Hall of Spins? It’s not for everyone, but some great prizes could be coming your way if you dare to enter. Get 3, 4 or 5 scatter symbols to enter – there are four different features here, one for each god, and as you get multiple entries into the hall, you’ll gradually unlock them all. The first feature is Valkyrie – she’s available from the very first time you trigger the bonus. She’ll give you ten free spins, with all wins multiplied by 5x. Her free spins can be retriggered too. From the fifth trigger is Loki. He’ll give you 15 free spins, with the Wild Magic Feature too. This feature randomly turns symbols into additional substitutes, and 2, 3, 4 or 5 scatter symbols will retrigger 1, 2, 3 or 4 free spins respectively.

Next up is Odin’s feature, which you can unlock from the tenth trigger. There are 20 free spins on offer here, with the Wild Raven Feature too. This feature can randomly turn symbols into 2x or 3x multipliers, and if both ravens land, you can be awarded a 6x multiplier! Finally, if you trigger the bonus 15 times, you’ll be in line for Thor himself. He gives you a huge 25 free spins, with Rolling Reels – consecutive wins will increase the multiplier up to 5x, and you can be awarded multiple consecutive wins!

Conclusion

With much more to entice you in than the original Thunderstruck slot, Thunderstruck II will keep you occupied for a while. There are quite a few different features here, with The Great Hall of Spins in particular catching the eye – it’s no surprise that this is such a popular slot with the features on show! Combine that with a decent RTP of 96.65%, and you can see why so many people flock to Thunderstruck. It’s simply a rather enjoyable slot with some good visuals too.
