This one is ancient! Not just in its theming – based on Viking-style Scandinavian myths and legends – but also in its age. This Thunderstruck slot game was released in 2004.

And yet, it remains popular and played by lots of players. In 2019 it was recorded in well over a third of UK casino sites.

That’s a great record for a game in an industry that is obsessed with novelty. That is something of a chimaera though. The fact is that the shells of games change an awful lot, but the underlying machinery of most online video slots wouldn’t puzzle a time-traveller from any casino from about the 1960s onwards.

So Thunderstruck slot has earned its place in the pantheon of games. It’s slightly old-fashioned looking, but there can be no doubt that Thunderstruck casino slot delivers an experience that players like, with its free spins and multipliers offering prizes that are very up to date.

But should you get out your thunder hammer and get striking?

Microgaming – The Developers of Thunderstruck Slot

Microgaming are behind nearly 500 slots in the market at the moment. Their slot games appear in nearly 500 casino sites in 24 countries.

The company is based in the Isle of Man, a part of UK territory with slightly different laws from the mainland. The company is owned by Apricot Investments Ltd.

Microgaming are fully licensed by the UK Gambling Commission, so you can play their games with confidence that you are getting a legal and honest experience.

In business since 1994, Microgaming pump out new slots all the time. They also produce casino and table games, and whole casino sites, which are usually operated by branded, independent companies.

Microgaming has twice held the record for the largest payout from an online video slot.

The Facts and Figures

If 2004 is a long time ago, the 96.1% theoretical return to player Thunderstruck offers its players is perfectly acceptable by the standards of 2019. Most games currently offer somewhere over 96% as their RTP, so this is at the lower end of that scale, but only marginally. The game’s “medium” variance rating also means you should expect a very typical, average experience in terms of pay-outs from Thunderstruck by Microgaming.

The top prize advertised is 10,000 coins. Betting runs from 0.01 coin to 1 coin. These figures should translate directly into pounds, but always check prize figures, betting levels, and limits on the machine you’re playing.

The standard five by three layout is in force, with just nine pay lines, which is quite low. You can play this game across desktop, mobile, and tablet devices, but you will need Flash, which you may need to enable or update in your browser.

The Game

Thunderstruck Slot

The game is simple to play, but the controls do look a little dated.

The player’s balance is shown at the left of the screen, you can then select expert mode and click for help to the right. A row of indicator windows show pay lines, coins bet, bet total, and win amounts. Underneath that a plus and minus button allows you to set figures after you have clicked to “select lines”, “select coins” or maximise the bet. At the bottom right of the screen is a blue spin button.

How to Win

Click on the “view pay-out” button for a paytable, which shows:

Cards from 10 to Ace, which pay from 5-times stake for three 10s, Jacks, or Queens to 100-times stake for a full set of five.

Kings pay 5, 50, and 125-times stake, and Aces pay 10, 50, and 125-times stake.

Above these symbols are a horn, a lightning bolt, a hammer, a hand, and a castle. These pay from 10-times stake to 250-times stake for the horn and lighting strike. The hammer and the hand pay out from pairs of symbols upwards: paying from 2-times stake to 750-times stake. The castle pays 15, 100, and 400-times stake.

Thor himself is a wild symbol and pays 10, 200, 2,000, and 10,000-times stake.

Goats are Scatters, and they pay out from 2-times stake to 500-times stake.

Thunderstruck Slot Bonuses

In the base game, there is a gamble feature that you can double or quadruple wins with. The Thor wild also doubles wins completed with this symbol as a wild.

The scatters award 15 free spins. All wins in the free spins round have a 3-times multiplier. Free spins can be triggered again during the round.

The Verdict

There is no denying the fact that Thunderstruck casino slot has some old-fashioned aspects to it. The control layout feels a little clunky, as is the presentation of the paytable (hidden behind a button that most machines have now discarded).

The game symbols and visual style are probably old enough that they’ll be back in style as ironic, retro fashion items soon!

None of these bothers us particularly, because this is another quality Microgaming title that has earned its 15 years of life.

The game plays nicely, with some interest in the wilds and the gamble feature on your wins, an old fashioned feature that we’d love to see come back into fashion because it’s wonderful fun, and potentially very lucrative!

The free spins round is great, and with those tripled wins, we make the actual possible top pay-out 30,000 coins, if all those wilds click into place.

The mechanics of some parts of the game might look a little creaky, but there’s nothing outdated about the rewards this game could offer or the actual game playing experience. We like the atmosphere of magical realism!

If you like Scandinavian myths and legends then we recommend you give Thunderstruck casino slot a spin and if it’s to your taste then you’ll be delighted to know that there’s a sequel on the market in 2019. That if nothing else shows that this game has far from aged, but perhaps has matured!
