Create AccountCan you hear the suspense-building riff of AC/DC’s ‘Thunderstruck’? Because here’s an online video slot just as thrilling as the opening of that rock number. We’re of course talking about Thunderstruck II (also known as Thunderstruck 2) the epic sequel to the successful mythology-themed slot from Microgaming. Excitement seekers can join Valkyrie, Odin, Loki and Thor right here at PlayFrank Casino, in a gaming experience that will leave you…*drums*...Thuuunderstruck.
It’s not difficult to see the appeal of Thunderstruck II, an online slot which takes you on a journey to Asgard while tempting you with Valhalla riches. The mysterious soundtrack includes dramatic music of lore and legends, and the game’s gorgeous illustrations bring to life epic characters from Norse mythology. But besides being a visual delight of Norse patterns and Viking imagery, this Microgaming slot will impress with its truly gripping game features - most notably, its four free spin bonus rounds.
Thunderstruck II’s special free spins feature offers a diverse number of ways to win, and your chances of a payout increase the more you progress within the game. By offering the unique advantage of saving your progress until the next time you play, Thunderstruck II makes it easy for lovers of PlayFrank online slots to unlock exciting bonuses over extended periods of time.
Once you’ve chosen your total bet based on a coin size from 1-10 (which will correspond with a bet between a minimum $0.30 and a maximum $16), you simply click the ‘SPIN’ button and watch the reels do their magic. The lower value symbols are the card symbols (9,10, J, Q, K & A), while the higher value ones are the Nordic gods themselves, Loki, Odin and the highest value Thor. Wins are paid out when you land from 3 to 5 matching symbols in a row on the same payline. The maximum payout for each are as follows:
| Symbol | Coins for 5 on a Payline |
| 9 & 10 | 100 coins |
| J & Q | 125 coins |
| K & A | 150 coins |
| Viking Ship | 250 coins |
| Valhalla | 250 coins |
| Valkyrie | 350 coins |
| Loki | 400 coins |
| Odin | 450 coins |
| Thor | 500 coins |
The Thunderstruck II logo is the Wild and can substitute for any symbol except the Scatter, which is represented by Thor's hammer.
You can click on ‘View Pays’ to see the payouts you’ve previously achieved (they’ll be featured in gold on the payout table). Thunderstruck II is a medium variance slot with a maximum payout of 8000x your stake and an RTP (return-to-player) at a very reasonable 96.65%.
There’s a lot of action to be had in Thunderstruck II; a slot which genuinely offers a vast number of ways to win.
Players enter The Great Hall of Spins by triggering the random Wildstorm symbol which, when struck, can substitute every symbol (except the Mjölnir Scatter symbol) as well as turn 5 reels wild.
The Scatter, meanwhile, is symbolised by Thor’s hammer, Mjölnir, and having this symbol land on three or more reels will allow you to enter The Great Hall of Spins. Depending on the number of triggers you’ve activated, you’ll have the chance to play up to four different levels based on the slot game characters; Valkyrie, Loki, Odin and Thor. With its achievement-based slot model, you unlock these free spin bonus rounds the more you play the game.
Valkyrie awards 10 spins where wins are multiplied by 5x, and her round is available on the first trigger.
Loki awards 15 spins with Wild Magic symbols. When these symbols land on the third reel, it will turn other symbols into random substitutes. If retriggered, this feature will allow up to four additional spins.
Odin awards 20 free spins with a Wild Raven feature which randomly turns symbols into multipliers of either 2 or 3. However, if two Wild Ravens appear on the reels, players are awarded a multiplier of 6x.
Thor is unlocked at the 14th trigger and awards 25 spins with a Rolling Reels feature, which will award multiple consecutive wins that can increase the multiplier by a maximum of 5x.
The more you play, the stronger your odds of reaching the Thunderstruck II bonus rounds. And don’t worry - with the game’s achievement structure, Thunderstruck II will remember your progress for the next time you revisit its world of mythic sagas. To make sure your progress is saved, always play the video slot through your PlayFrank Casino account.
The first free spin bonus round you’ll be able to unlock is that of Valkyrie, but the more you play the closer you’ll come to entering Thor’s exhilarating Great Hall of Spins, which is the most exciting feature in the whole slot and where you can expect the biggest wins.
