Thunderstruck II is an online slot based on Norse mythology. The game has a 5×3 reel layout with 243 paylines and features familiar Norse characters including Thor, Loki, Odin and Valkyrie. Released back in 2010, the game’s reels feature Norse patterns as well as a cold, stone appearance.

Symbols in the game include a Norse boat, Asgard as well as the generic numbers and letters. The slot is one of Microgaming’s most popular games and continues to be played today. But has it stood the test of time? Let’s find out.

How To Play

To access Thunderstruck II, all you need to is register at a Microgaming casino and sign in. Once that’s all done and you’ve made your first deposit, you simply need to search for the game or scroll through the website until you find it. After you’ve launched the game, you’ll need to click the ‘Spin’ button to start the popular game and get hooked.

It’s possible to adjust your bet if you want to wager more or less. To do this, you’ll simply need to click the ‘Coins’ button to adjust the number of coins wagered and the ‘+’ and ‘-‘ buttons to increase or decrease the overall wager. Unlike most other online slots, Thunderstruck II does not feature an autoplay button.

Special Features


Compared to most online slots released today, Thunderstruck II’s graphics are somewhat boring. The game features simple cartoons of Thor, Loki, Odin and Valkyrie as well as its generic symbols. However, the sound effects help make up for that completely.

Thunderstruck II’s logo represents the Wild symbol and can substitute all other symbols except the Bonus which is represented by Mjolnir, Thor’s magical hammer. Landing three or more Bonus symbols will trigger the game’s bonus feature known as The Great Hall of Spins.

The Great Hall Of Spins

Landing three, four or five Bonus symbols will trigger this special feature which is made up of four different levels. Triggering the feature multiple times unlocks new levels within the bonus game and rewards you with better prizes. But what are the levels?

Valkyrie: The Valkyrie bonus is available on the first trigger and provides users with 10 free spins. All wins made through the Valkyrie bonus game are multiplied 5x and landing additional Bonus symbols will help retrigger free spins.

Loki: The Loki bonus is available on the fifth trigger and provides users with 15 free spins. During the Loki bonus game, the Wild Magic feature will be in effect and landing a Wild Magic symbol will randomly transform a symbol into a winning substitute. On top of that, landing two, three, four or five Bonus symbols will earn you one, two, three or four free spins.

Odin: The Odin bonus is available on the tenth trigger and provides users with 20 free spins. During the Odin bonus game, the Wild Raven feature will be in effect, which can randomly turn symbols into a x2 or x3 multiplier. If both Ravens land, you’ll be awarded a x6 multiplier.

Thor: The Thor bonus is available on the fifteenth trigger and provides users with 25 free spins. During the Thor bonus game, the Rolling Reels feature will be in effect and consecutive wins will increase a multiplier from x2 to x5, helping you earn some big wins.


The Wildstorm feature helps make the base game a lot more fun as it can randomly strike, turning up to five reels wild to help you form winning combinations. However, it’s important you understand that you cannot trigger the free spins feature during the Wildstorm feature.


It’s so easy to see why Thunderstruck II is so popular. The slot is based on Norse mythology and features some appealing visuals as well as a great soundtrack. The Great Hall of Spins will help keep players occupied along with the Wildstorm feature, which is bound to help make some bigger payouts.

Thunderstruck II benefits from Microgaming’s high-quality development and has become an iconic game. While it looks a few years old and there certainly are more modern games to play, Thunderstruck II will forever remain special for many online gamblers.
