Thunderstruck II is an online video slot game developed and released by Microgaming slots. First launched in May of 2010, this game has become one of the most played online slot games at leading online casinos today. The reasons for this are simple: the game features five reels and an impressive 243 ways to win. You can bet a maximum of 300 coins at a time (as much as £15 per spin). The game's Norse mythology theme adds to its allure with impressive imagery of Nordic gods like Loki, Valkyrie, Thor, and Odin.
The small 1000 coin jackpot may be a bit less than some gamers typically prefer, but the overall gameplay really lends strong appeal and the potential payouts are very impressive, especially in the later levels. The logo for Thunderstruck II is the game's wild symbol. It can be substituted for all other symbols with the exception of Thor’s Hammer. The wild symbol also does not apply to the randomly-triggered Wildstorm feature. This feature earns the player one free spin with up to five wild reels. If the player gets 4 or more wild reels, a huge payout is about to happen.
The Great Hall of Spins
Thunderstruck II's main feature is its Great Hall of Spins. It offers free additional spins with a unique multiple-level element. To access this feature, the player needs to achieve three or more Bonus Hammers. There are a total of four levels to this bonus feature which can be triggered by entering the bonus round a given number of times.
The first Norse deity players meet is Valkyrie. His feature is triggered on the first through fourth feature triggers. The player is awarded 10 free spins with a 5x multiplier on all wins. Players can re-trigger even more free spins at this level.
Next up is Loki. His feature is triggered on the fifth through ninth feature triggers. Players are awarded 15 extra spins and unlock the Wild Magic feature. On the game's middle reel, Wild Magic symbols transform other symbols into even more wilds.
Odin's feature appears next and is available on the tenth through fourteenth feature triggers. Players unlock 20 free spins here along with the Wild Raven feature. The raven symbols turn other symbols into either 2x or 3x multipliers at random. Unlock two of these and the player enjoys a 6x multiplier.
Finally, the player encounters Thor. His feature is available on every feature trigger from number fifteen onward. At this level, players 25 additional spins on Rolling Reels. Consecutive wins progressively increase the multiplier, starting at 2x all the way to 5x. There is a potential of unlocking a 5x multiplier on each and every spin at this level.
Once all four levels are triggered, players have the option to choose to play on level they wish. Simply return to the Great Hall of Spins and select the desired level. Best of all, Thunderstruck II has a memory feature that allows the player to pick up the game wherever he or she left off. A progress bar lets the player know how far he or she has progressed in the game.
Although Thunderstruck II is considered a medium variance online slot game, it is a very well balanced game that is capable of producing some large and very impressive wins. Rolling Reels and Thor in particular have potential to give the player some massive returns. The former is such a fan favorite that it is used over and over in games developed by Microgaming Slots – creators of such online casino favorites as Avalon II and Immortal Romance.
