As you can see from its name, it is the sequel for the successful Microgaming Norse Mythology themed game launched back in 2003 Thunderstruck. The new installment updates on graphics and brings many new features to the table. The blend of amazing visuals, Norse themed music and a variety of bonus features is the main reason behind the popularity of this slot even to this day.

This slot has 5 reels, 3 rows and a whole 243 paylines which make the gameplay more exciting with so many unexpected outcomes that are bound to happen. The bet range for Thunderstruck II starts from C$0.30 per spin and the maximum bet can’t go any further beyond C$60. The payouts are worth it as the game is filled with multiplier bonuses and the main jackpot may get you 2,400,000 times your initial stake.

Gameplay & Bonus Features


Thunderstruck features a huge variety of low value and high value symbols. Lower symbols consist of the classic A, K, Q, J, 10 symbols, while the higher value symbols are represented by the gods of Norse mythology, characters like Odin, Loki and Thor brace the screen with their presence and bring a lot of earnings with them.

Players can unlock winning combinations by landing 3-5 of the same symbol on the winning reels, starting from the left reel and enjoying the payouts.

The Wild in this game is the Thunderstruck II game logo itself, this symbol has an ability to substitute any other symbol except for Scatters and help players to form winning combinations, and as a bonus, it will double your winnings on them.

Hammer of Thor takes the role of a Scatter. As mentioned above, it can’t be replaced by Wild to form winning combos, but if you get lucky enough to get 3 or more, you will unlock a Bonus Feature which will award you with Free Spins.



The first future in Thunderstruck is a Wildstorm feature that can happen anytime during your gameplay. When you trigger it, the lighting bolt will strike and convert between 1-5 reels into the Wild Symbols. If you get a 5-reels full Thunderstruck logos, you will win a jackpot worth 2,400,000x your initial bet.

The Great Hall of Spins

The Gods of Asgard are generous and allow the chosen ones to enter the Bonus Mode called The Great Hall of Spins when you land 3, 4 or 5 Hammer of Thor scatters that will award you with either 1, 2, 20 or 200x multiplier on your stake.

If you manage to enter the Bonus Mode, multiple trials will await you. The more times you enter the Hall of Spins, the more options to win Free Spins you will get.

On your first time entering the Hall of Spins, be prepared to meet Valkyrie right away. Valkyrie will award you with 10 Bonus Spins and 5x multiplier on our wins. The feature can be activated more than once and will provide you with extra Free Spins up until you hit 20.

Once you will trigger The Great Hall of Spins feature for the fifth-ninth time, trickster Loki will appear to test your might. From him, you will get 15 Free Spins and the unique Wild Magic feature. It has a potential to substitute other symbols to wilds if it lands on reel 3. If you manage to land 2 scatters or more, you will earn up to 4 FS extra.

The grand Odin will bless you with his grace once you activate the feature for 10 times, and will award you with a whole 20 Free Spin Bonus and Wild Raven feature. Odin’s raven companion will replace random symbols into 2x or 3x multipliers, and if you get two ravens at the same time, you will get a 6x bonus to further boost your winnings.

The last of the gods you will encounter is Thor. He will appear if you access the Great Hall of Spins for 15+ times. Together with the God of Thunder, 25 Free Spins and Rolling Reels bonus will await you. Rolling Reels feature will provide the player with a multiplier on consecutive wins, from 1x and up to 5x.
