Whilst some might argue that it’s the graphics on Thunderstruck that show this machine’s age, we still think there’s something very charming about the whole look to this game. It uses rich deep colours on the reels and all of the base-game symbols have a rough and rugged look to them, which fits in incredibly well with the theme. The animations are fast paced and smooth, adding to the action – making this a machine that’s able to hold its own against the slots of the moment.
Sound-wise, there’s something very addictive about the strange rumbling drum rhythm that plays throughout your time on the reels of Thunderstruck. It comes with a full arctic wind accompaniment helping set the scene of a cold, desolate, Norse tundra where you’re no doubt sheltering yourself from the harsh elements as you crouch down to take some spins on this classic slot machine.
The base game in Thunderstruck is surprisingly simple. It plays over a standard casino slot set up of five reels with nine pay-lines on which you can make your wagers. Here you can adjust your coin size and the number of lines you’re betting on to come up with your own bespoke gambling experience. You might think that nine lines sounds a little low in today’s era of 243 ways to win machines, however the low winning potential on the grid does mean that every combination available pays out some handsome prizes.
There are two special symbols on the reels that can help you go about your winning ways. The first is the scatter symbol – two rams – that holds the key to Thunderstruck’s bonus round. The second is the Thor wild multiplier, which not only helps you complete combinations on the reels, but also doubles the value of the associated prize.
Thunderstruck allows you to take any small win you hit in the base game and gamble it on a fair game of card turn. Here you can try to guess the colour of the next ace off a pack to double your money, or if you’re feeling incredibly luck you can try to predict the suit of the next card in order to get a four times return on your stake. There are many slots out there that feature this kind of gamble game, but it should present no problems to both novice and experienced punters.
Finally, and we’ve saved the best till last, there’s the Thunderstruck free spin round. As we hinted at earlier this is activated when you hit three of the special ram scatters anywhere in view on the base-game grid. This takes you to a second set of reels where all your wins are tripled for the duration of the bonus and you’ll receive 12 free spins. This bonus can also be re-triggered if you’re lucky enough to hit three ram scatters in the feature, adding a further 12 spins to your count.
