Thunderstruck II SlotThunderstruck II is a highly popular 5-reel, 243-way video slot by Microgaming which is based on the myths and tales of Norse mythology. The game attracts thousands of casino players with its stunning design, four bonus games, and the opportunity to win up to 2,4 million coins.

This slot was launched by Microgaming in 2010 as a sequel to the then-popular Thunderstruck game, but it included more advanced graphics, well-portrayed theme, and amazing bonus features. The reels in Thunderstruck II are set against a grey background and are decorated with Norse art elements. They look as if being carved in stone, while the symbols include iconic images from the Viking culture and mythology such as longships and Thor’s hammer.

Although the game has a seemingly standard design of 5 reels and 3 rows, there are very few standard things about it. It features 243 ways to win, which means that any left-to-right combination that starts from the first reel will win. A random feature turns the reels Wild, while different bonuses can be unlocked over the course of the game.

All 243 ways to win are permanently active and the line bet is always multiplied by 30. Players can wager up to 10 coins in sizes of 0.01, 0.02, and 0.05 credits. While the lowest bet is just 0.30 credits per spin, the maximum bet reaches 15.00 credits.

Special Symbols

Along with the themed icons on the reels, there are also generic playing card symbols from Nine to Ace, which occur most commonly and offer the lowest payouts. As higher-value symbols, we can see the Viking longship and Asgard, the heavenly home of the gods connected to the world of humanity by a rainbow bridge. There is a beautiful Valkyrie and several gods are also represented – Loki, Odin and Thor.

The game includes the standard Scatter and Wild symbols, with the hammer of Thor functioning as a bonus-triggering Scatter icon. It forms its own combination when 2 or more hammers land anywhere on the reels. And 3 hammers on the reels award entry to The Great Hall of Spins, which is the main bonus feature of this slot.

The Wild symbol is the Thunderstruck II logo which offers a separate payout. The Wild completes winning combinations by replacing all symbols in the game, except for the Scatter. At the same time, it also doubles the winnings when substituting. Players who land 5 logos on all 5 reels are awarded the jackpot of 1,000 coins.

Bonus Games and Features

The first interesting feature in this slot is, undoubtedly, the 243 ways to win payout system. Instead of having fixed lines where symbols would need to land, this system gives a payout for any 3-symbol combination which appears on adjacent reels from left to right, starting with the leftmost reel. Another very exciting feature is the Wildstorm feature which triggers randomly during regular spins. When it kicks off, any number of reels may be turned completely Wild, which considerably increases players’ winning chances.

The main bonus feature in Thunderstruck II, however, is The Great Hall of Spins which becomes more lucrative the longer this slot it is played. It activates when 3, 4, or 5 Scatter hammers land anywhere on the reels. Players are awarded the Valkyrie bonus which comes with 10 free spins and a 5x multiplier. This bonus can be re-triggered and those who play the game long enough to enter The Great Hall of Spins 5 times are given access to the second bonus.

This is the Loki bonus, which offers 15 free spins with a Wild Magic feature. The extra Wild Magic feature is triggered by its corresponding symbol – when that icon lands on reel 3, it will transform random symbols into Wilds. Players who land more Thor’s hammers during these rounds will receive up to 4 additional free spins.

When players open the bonus feature for the 10th time, they unlock the Odin bonus. The white-bearded god awards 20 free spins with the Wild Raven feature. His ravens turns icons into 2x or 3x multipliers on a random principle, while both ravens appearing at the same time may result in a 6x multiplier.

The fourth level players can progress to is the Thor bonus, available when The Great Hall of Spins triggers 15 times. During this bonus, players receive 25 free spins with Rolling Reels. This extra feature starts with a 1x multiplier but with each consecutive win, the multiplier increases reaching up to 5x.


With all those free spins features, Thunderstruck II is a very attractive option for casino players even though it does not offer a progressive jackpot or huge payouts during the base game. While the regular 1,000-coin jackpot is quite low, compared to most video slots today, the bonus rounds can be extremely lucrative. In fact, players can win up to 2,4 million coins which even with penny bets, is a real fortune when we convert it to real money. Of course, the more profitable bonus features are unlocked after many spins. But this is exactly where the temptation lies – you keep playing and the more you play, the greatest the rewards become.
