Thunderstruck 2 Review

The original Thunderstruck is a legendary game from the early years of online pokies. It's not particularly flashy, but to this day remains an interesting and enjoyable game to play. The sequel, Thunderstruck II, is a natural progression from the original, showing the huge leaps forward taken by slot machines in a very short period of time. Is Thunderstruck II worthy of its progenitor's legacy as one of the best pokies ever made, or is evocative of real thunder, all sound and no fury?

Gameplay and Design

Thunderstruck II is a 243 ways pokie, meaning that as long as symbols are on adjacent reels, they will match, no matter where they appear. This makes it an excellent game for beginners and seasoned pros alike; players don’t need to worry about paylines and they can maximize their winnings.

When you play Thunderstruck II, you’ll encounter two different varieties of symbols on the game’s reels. Playing card symbols, such as 9, 10, and A, make up the majority of the symbols, but as you may expect, they are also worth less than other symbols. Themed symbols, such as the Viking longboat or the rainbow bridge to Valhalla, are less common but generate larger winnings when matched.

There are also two symbols with unique properties.

The Thunderstruck II logo is the Wild symbol, and can substitute for any other symbol, with the exception of the Scatter symbol. A feature unique to Thunderstruck II is that any matches completed using the Wild symbol earn a doubled payout, making them even more useful than they usually are.

Thor’s hammer, Mjölnir, is the Scatter symbol. If you’re lucky enough to spin at least three Scatter symbols anywhere on the reels, you’ll be taken to Thunderstruck II’s bonus feature, the Great Halls of Spins, which we discuss in the following section.

Lastly, the Wildstorm bonus game is activated at random as you play Thunderstruck II. This feature replaces entire reels with Wild symbols, up to all five reels. While it’s not likely to cover your entire board, having an extra reel or two of Wild symbols can be very useful in and of itself.

Like its predecessor, the design of Thunderstruck II is subtle and minimalist. The game’s soundtrack is subdued, with the occasional epic swell coinciding with a big win. The animations aren’t big and bombastic, preferring to go for a more realistic approach. It may not be as colourful as some of Microgaming’s other pokies, but it’s just as well-made.

Promotions and Bonuses

The Great Hall of Spins is where you’ll be able to access the different bonus rounds that Thunderstuck II has available, and you can get there by activating three Scatter symbols across the game’s reels. Initially, you’ll only be able to claim 10 free spins, but you unlock a new bonus game every five visits. Bonus games are themed around different characters from Norse mythology, including Loki and Thor, and each has their own rules and conditions. Odin’s bonus round, for example, sees random symbols transformed into Wild symbols, with wins incorporating them multiplied up to six times.

There is a hierarchy to the bonus games, with the most impressive, Thor’s, being available only after you’ve visited the Great Halls of Spins 15 times. While it does reward players that have put time and energy into playing Thunderstruck II, the inherent randomness of pokies means that some players may never get the chance to visit the Great Hall of Spins once, let alone 15 times. If you have the time and bankroll to achieve that goal naturally, go for it, but there’s also nothing wrong with any of the earlier bonus games.

In addition to the free spins you can earn by playing Thunderstruck II, some online casinos may offer them as a casino bonus, typically through a welcome or deposit bonus. Make sure to read the bonus terms before you sign up, either to play at an online casino or to claim a bonus at a casino you already frequent, to learn how much real money you’ll need to add to your account for the minimum deposit.

It’s also worth noting that different online casinos offer different bonuses. A promotion at PlayAmo Casino, for example, will differ from a promotion at JokaRoom. How much bonuses influence your decision to sign up for a specific casino is ultimately up to you, but if you’re looking to play Thunderstruck II or any other specific game, make sure it’s offered before you sign up.

Just like the original, the Thunderstruck II pokie was developed by Microgaming, one of the leading names in casino games and software. Founded in 1994, the UK-based company has been responsible for some of the most popular and beloved games in the history of online pokies.

Even a small list of their games reads like a greatest hits collection, including Immortal Romance, Cash Splash, and the game they hold a Guinness World Record for, Mega Moolah. The creativity and passion they bring to every title makes Microgaming simply one of the best casino game developers around today.
