Can’t you hear that thunder?

There isn’t much in the way of sound, so keep an ear open when you spin the reels. There’s a tense – if a little simplistic – tune playing when you spin, but a crash of lightning when you find Scatter Rams and a bit of thunder when you get a win. It certainly grabs your attention, and perhaps is even more emphatic due to the lack of music elsewhere on the slot.

There’s a little more to the graphics, but if you’re used to high-quality video slots, you may still find this game a little lacking. There’s a background of a dark, stormy sky which looks pretty realistic, and some cartoon symbols too. Letters and numbers are golden against the stone they’ve been carved into, and Thor’s hair waves in the wind when his symbol pops up. There’s quite a rough-around-the-edges, Viking-style quality to the graphics, so they aren’t as refined as in other slots but definitely fit the theme well.

Storming across the paylines

Nine paylines might seem a little on the low side, but luckily all symbols pay out well. The most valuable symbols have a strong Viking theme, like the staff and hammer of Thor himself, as well as a castle and a crash of lightning. From just a 90p spin, you can win £75 by matching five hammers, while even the lowest-value symbol – the humble 9 – could see you £10 up from the same 90p spin.

The paylines all pay from left to right, and as there are just nine of them, they’re fairly typical for a slot. Of course, only the highest win is paid per line, and all wins pay from the leftmost reel. Scatter symbols pay out too, although they aren’t multiplied by credits staked per line like the other wins – instead, 5 of them will see you win 500x your bet!

When the weather goes wild

Although there isn’t an abundance of bonus features in this Quickfire slot, the free spins feature is one to look out for. Get 3 or more Scatter Rams to win 15 free spins, and you’ll be able to triple your wins too! You even have the chance to activate a further 15 free spins while you’re playing with the first lot, so you could be on these spins for a while! All bets and lines played are the same as on the game which triggered the feature, so of course that part depends on you…

You might also see Thor himself pop up from time to time. He pays out pretty well, with the potential to win £1,000, and he substitutes for all other symbols apart from scatters. Any win in which he acts as a wild symbol will be doubled too, so if he was to help you get five hammer symbols in a payline, you could win £150 from just a 90p bet!

Conclusion

There’s a lot to like about Thunderstruck, particularly if you don’t enjoy games where the glitzy features threaten to overshadow the gameplay. Although it’s basic in parts, the theme is still fun and there’s enough to hold your attention. Meanwhile, the RTP or return-to-player is reasonable at 96.1%, and the medium-high volatility of this Microgaming slot makes it suitable for players who don’t mind taking the occasional risk. Overall, it’s a fun slot that’s definitely worth trying out.
