When Microgaming announced at the ICE Show in London in January 2010 that they were going to release a sequel to one of the most popular online slots - Thunderstruck, it wasn't a surprise. The original Thunderstruck slot continues to turn heads since its release in 2004, and its predecessor is just as popular. Thunderstruck II is an enhanced version of the original, featuring 5 reels and 243 permanently enabled winning ways. More so, this slot features 4 different, yet all highly-rewarding, bonus events with a chance to win up to 2.4 million coins.
Microgaming has the sounds and graphics right in Thunderstruck II, which they have also balanced out with a dynamic gameplay and high potential for huge wins via innovative features. The new Paytable Achievements feature allows players to unlock symbols by completing all payouts for each symbol. Watch your paytable turn to gold and keep track of your winnings with the Paytable Achievements feature.
Thunderstruck II offers a much more detailed theme and striking graphics than its predecessor. Various Nordic gods, including Loki, Valkyrie, Odin, and Thor will greet you on the reels. Other symbols include Thor's Hammer (Bonus symbol), the Thunderstruk II logo, the Ship, and Thor's Home. The generic poker symbols (9 through Ace) are also available (even though they're better suited for games like Jacks or Better video poker).
The Thunderstruck II Logo symbol is wild, and it substitutes all other symbols on the reels except Thor's Hammer. Furthermore, the Logo will double your wins whenever it substitutes in a winning combination. The Logo ceases to be wild during the Wildstorm Feature, a randomly triggered feature that will turn as many as all of the reels to wilds (you cannot trigger free spins during this feature).
The Thunderstruck II online video slot is loaded with features and bonus action, all of which are detailed below.
The Great Hall of Spins is the main feature in Thunderstruck II. It will help you unlock the multi-level Free Spins bonus features. You need to get 3 or more Thor's Hammer icons on the reels to trigger this feature. Multiple entries into the Great Hall of Spins will sequentially pave the way to more bonus features.
Triggering the Great Hall of Spins between your 1st and 4th bonus feature trigger will enter you into the Valkyrie Bonus feature where you will be awarded with 10 free spins, and all wins will be multiplied 5X. You can retrigger more free spins during this feature.
The Loki Bonus will be triggered between your 5th and 9th bonus feature triggers. In this bonus round you will be awarded 15 free spins with a Wild Magic Feature. Look out for the Wild Magic symbol on the reels as it will randomly transform symbols into additional wilds, much like the shifting wilds feature that can be found on many casino games these days. More so, 2, 3, 4, or 5 of Thor's Hammer will trigger 1, 2, 3, or 4 free spins, respectively.
You will trigger the Odin Bonus feature between your 10th and 14th trigger of the bonus feature. You will be awarded with 20 free spins with the Wild Raven feature. Odin's Raven's will randomly turn symbols into 2X and 3X multipliers. You will be awarded with a 6X multiplier if both of Odin's Ravens appear on the reels at the same time.
The last and most rewarding Free Spins feature is Thor's Bonus feature which you will trigger in your 15th trigger of the bonus feature. In this feature you will be awarded 25 free spins with a Rolling Reels feature where consecutive wins will increase the multiplier up to 5X. The Rolling Reels have the ability to award you with multiple consecutive wins.
Once you trigger all levels then you can choose to play whichever you like whenever you trigger the Great Hall of Spins feature.
Lines per bet start at 0.01 and go up to 0.25. There are 10 coin levels, so a max bet will cost you 75.00 credits. There are no slot machine paylines, but rather 243 ways to win.
Thunderstruck II is a medium variance slot that is well balanced with a potential of producing really big wins. There are a lot of extras added to this slot, one of the most exciting being Thor's Rolling Reels feature that often awards multiple consecutive wins. Other Microgaming slots with this feature include the blockbuster Avalon and the higher variance Immortal Romance.
