Thunderstruck II Slot Review

Marvel Studios debuted the first of several successful “Thor” movies in Canada back in 2011, but online slot developer Microgaming was ahead of the curve. Microgaming launched the Norse mythology-themed online slot sequel Thunderstruck II one year earlier.

And indeed, Thunderstruck II positions Thor himself – the Norse god of thunder and lightning – at the heart of the online-casino action in Canada.

Reel symbols include his mighty hammer Mjolnir, his heavenly home Asgard, and his mischievous brother, the trickster god Loki. But just like in the movies, Thor takes centre stage, so when three Mjolnir symbols hit the screen, get set for a series of free-spin bonus rounds.

As a five-reel game featuring 15 symbol spaces and a whopping 243 “ways” to win – rather than conventional paylines – learning how to play Thunderstruck II online slot might seem like a chore.

But after firing up just a few spins on this Microgaming slots classic, even online slot rookies will quickly get the hang of things. Those 243 ways to win simply reflect any string of three or more matching symbols, beginning with Reel #1, that move left to right across the screen.

Thunderstruck II uses the Mjolnir hammer as its bonus symbol, with three onscreen triggering a series of free spin rounds. And the Thunderstruck II logo symbol acts as a wild, substituting for everything else but Mjolnir and applying a 2x multiplier on any winners.

FAQ Section

Is it safe to play online slots in Canada? 

Playing at online casinos is not only safe, but it’s also easy and perfectly legal due to Canada’s lack of federal legislation concerning online casino players. In fact, provincial governments such as British Columbia, Manitoba, and Quebec even license online slot sites of their own. All things considered, when you choose a reputable operator, playing online slots in Canada is as safe as spinning in your local casino.

Can I win money playing online slot games?

Of course, you can, that’s the beauty of any gambling game after all. In the case of Thunderstruck II, the top jackpot payout – triggered when you land five of the game’s logo symbols – comes to 1,000 coins for every coin you wagered.

But with 243 unique ways to win on every spin, Thunderstruck II ensures a steady stream of smaller payouts along the way. Landing three of the Valkyrie warrior woman symbols is good for 20 coins, while five Loki symbols produce a 400-coin payout.

Can I play online slots for free?

One way to win money is to avoid losing it, which is why the free-play feature offered by most major online casinos is – as Thor might say – a godsend.

Simply visit your favourite Microgaming-powered online casino and pull up Thunderstruck II. Look for a button labelled “Free,” “Play Money,” or “Demo” and click through to enjoy as many spins as you’d like on the house.

Once you’ve tested the waters and learned the ropes, you’ll be ready to fire up your first real-money session.

What should I look for when choosing an online slot game? 

The first factor to consider when sizing up online slot games is the theme. Unless you enjoy the background music, video clips, symbol designs, and other extensions of the theme, any slot can grow tiresome in a hurry.

Next up, look for slots that offer a high return-to-player (RTP) rate. This number is essentially the inverse of the house edge, so it reflects your theoretical return on every dollar wagered.

In the case of Thunderstruck II, the RTP comes to 96.65%, putting this game on the higher end of the online slot spectrum.
