There are a handful of online slot machines that undoubtedly rank in the top 5 most influental slots of all time. In that list you would probably find Starburst and Gonzo’s Quest, but also Thunderstruck and the sequel Thunderstruck 2. Both of these slot games have gained a massive following from all around the world and it is difficult to say which of the two games in the series is more popular.

Thunderstruck II has 5 wheels on 3 lines. In true Viking spirit, the symbols are painted by hand and represent Norse Gods, runes, Vikings and famous relics such as Thor’s Hammer, a.k.a. Mjolnir.

Why Thunderstruck II has become such a successful online slot can probably be traced to the outstanding free spins mode that you can unlock in the game. The Thunderstruck 2 freespins mode improves each time you activate it. In Thunderstruck 2 you don’t need to line up the symbols in a perfect straight line to win, you just have to get the same symbols on wheels that are adjacent to get a winning combination. This is the benefit of the 243 paylines system!

Thunderstruck 2 is one of the most popular slots of all time, and for good reason.

Features and symbols

In Thunderstruck 2, as in almost all online slots, your goal is to line up as many identical symbols as possible, but in this game it does not matter so much in which order they appear compared to other online slots. 5 reels, 3 lines and 243 paylines gives you plenty of opportunities to collect wins both big and small.

In Thunderstruck 2 you will notice that there are more symbols than in most other famous slots, there are in fact 14 different kinds. You could compare the symbols to a deck of cards and soon you will understand why. Here are the most common symbols:

  • Number 9 and number 10
  • Letters J, Q, K and A
  • Viking Ship symbol

Just like the cards in a standard deck of playing cards, Microgaming has chosen these symbols as the base symbols in this game. In addition to the them, you will find symbols containing images of Norse Gods, Mjolnir (this is the game’s Wild symbol), Valhalla and the game’s logo. The latter generates big bonuses and free spins if you are lucky. This is the payout for these symbols:

  • 3, 4 or 5 Loki symbols– you win 20 – 400 coins.
  • 3, 4 or 5 Odin symbols – you win 30 – 450 coins.
  • 3, 4 or 5 Thor symbols – you win 30 – 500 coins.
  • 3, 4 or 5 Thunderstruck 2 logos– you win 75 – 1000 coins.

You can win a maximum of 2,400,000 coins in Thunderstruck 2, which is possible only if you succeed in getting the Thunderstruck 2 logo on each slot in each reel and row. 15 symbols in other words. In addition, it requires that you have wagered 10 coins on your spin. If you have also chosen to play with a maximum coin value, you can win a over €100,000.

Wilds and Free spins in Thunderstruck 2

You are probably already familiar with what a Scatter symbol is, and in this game this symbol is represented by Thor’s Hammer. When you land on this symbol, the Thunderstruck 2 free play / free spins mode is activated. The more times you activate it, the stronger the effect will be. For each new free spins level, stronger and stronger Norse Gods will appear. Here are the Thunderstruck 2 freespins levels:

  • 1st free spins level Valkyrie – 10 free spins + 5x your wager.
  • 5th free spin level Loki – 15 free spins + Wild Magic that generates new Wilds.
  • 10th free spin level Odin – 20 free spins + Wild Raven that generates 2x and 3x multipliers.

As one of the oldest online slots that still appears in many casino top 10 list most popular slots, we can truly say that Thunderstruck 2 and its predecessor are living legends in the casino world. Perhaps it is thanks to the magical powers of the Norse Gods that the game is still kept alive. Or maybe it’s simply because this game is a perfect online slot with every feature you could ask for. The more successful you are while spinning the wheels, the bigger your free spins bonuses and multipliers get, you can also win big through the Wilds symbols in Thunderstruck II.

The Viking and Norse Gods theme is reminiscent of Nordic folk tales and epic battles between good and evil, perfect for those who want to escape reality for a moment or two. The quality of the music and graphics are high and Thunderstruck 2 is suitable for both new players and more experienced ones. However, don’t expect to win the biggest sums of money imaginable, as Thunderstruck II pays out a little less than some other popular slots. We look forward to what Thunderstruck 3 will offer us in the years to come. Will Thunderstruck III be as successful as its ancestors or are the glory days over for this series? We would like to see what Microgaming can come up with. There is definitely room for improvement here, even though Thunderstruck 2 is clearly an online slot that deserves praise and respect.
