Theme and Appearance
As Thunderstruck II was released in 2010, the graphics and animations are slightly dated; however, many gamblers believe that this gives the slot nostalgic charm. The reels are filled with theme-fitting symbols including A, K, Q, J, 9 and 20 royals as the low payers. You'll also find Viking longships and Nordic gods Valkyrie, Valhalla, Odin, Loki and Thor as the high payers. Thor is the most rewarding symbol, paying 16.67 your total stake for a top combination. The game's logo is the wild and substitutes for all other symbols bar the scatter. When the wild forms part of a win, your payout is doubled. As well as substituting for other symbols, the wild acts as a symbol in its own right and pays 33.3 times your stake for 5 on a payline. You also win this generous amount if you form a winning combo with 4 Thor symbols and a wild. All wins are formed from left to right, starting from reel 1.
Betting and Prizes
Depending on your bankroll and preference, you can bet anywhere between 30p and £15 per spin on this slot. Winning combinations are formed by matching 3 or more symbols on successive reels, starting from reel 1. In terms of prizes, the top payout is 2,400,000 coins. Obviously, the value of this will depend on your chosen coin value. If you're looking to win big, focus your attention on the Great Hall of Spins. During this feature, you can enjoy multipliers, multiplier Wilds and other innovative features to boost your winnings. The RTP of this slot is 96.65%, which is comfortably above the industry average of 96%.
Like most slots, Thunderstruck II comes with various bonus features including The Great Hall of Spins and the Wildstorm feature. Below, we explore these in more detail.
Thunderstruck II benefits from a randomly activated Wildstorm feature. When triggered, up to 5 reels can turn fully wild to boost your winnings. If luck is on your side, you could bag 1000x your total stake.
The Great Hall of Spins Features
The best thing about Thunderstruck II is the Great Hall of Spins feature. This is triggered by landing 3, 4 or 5 scatters anywhere on the grid. When you do, you'll activate the feature and receive 1, 2, 20 or 200 times your stake as a bonus. Unlike your standard Free Spins round, the Great Hall of Spins is a multi-level feature. There are 4 features on offer, which become available once you activate the Great Hall of Spins a certain number of times.
Valkyrie feature – this feature is available from the first trigger and awards 10 free spins with a 5x multiplier. Throughout the round, you'll have the chance to trigger additional free spins.
Loki feature – This feature is available from the fifth trigger and awards 15 free spins. It comes with the Wild Magic feature, which randomly transforms symbols into additional wilds. If you land 2, 3, 4 or 5 scatters during the feature, you can win 1, 2, 3 or 4 more free spins.
Odin feature – this feature is available from the tenth trigger and awards 20 free spins. It comes with the Wild Raven feature which randomly turns symbols into 2x and 3x multipliers.
Thor feature – finally, you have the Thor feature. This is available once you trigger the Great Hall of Spins 15 times. When you do, you'll receive 25 free spins with the Rolling Reels feature active. Whenever you form a winning combo, the multiplier increases by 2x to boost your winnings.
Once you've triggered the Great Hall of Spins 15 times or more, you can play any of the 4 features. To see how many times you've triggered the round, keep an eye on the progress bar at the top of the screen.
Thunderstruck II is another excellent slot from Games Global. A cult classic amongst gamblers, the game is medium variance and is all about the Great Hall of Spins feature.
