One of the fantastic aspects of this game is the lack of traditional paylines – instead, all adjacent symbols pay out from left to right, enabling 243 possible ways to win. Wilds, multipliers and varying levels of free spins are also up for grabs – stick around to find out more!
How to Play Thunderstruck II for Free
If you’d like to get a short preview of the game and try out all the features and extras it offers, most online casinos will give you a chance to play a demo version of almost every slot out there, precisely for this reason. Fancy doing a few free spins? Then look no further – we’ve got you covered with a practice mode version where you can spin with a play money balance for as long as you want. In case you do run out of funds – which we doubt you will – simply top up and keep playing!
–As we noted before, the theme of the game celebrates the old Norse myths of Odin and other gods of the pantheon, as well as the Vikings’ might and affinity for seafaring adventures. Wonderfully decorated, the play grid gives you a rundown of the most famous personages like Loki, Thor or Valkyrie, and the famous Hammer of Thor also makes an appearance as the Bonus icon. This slot is an upgrade of the Thunderstruck, a somewhat older and simpler game from the same developer, providing 9 paylines and fewer free spin features. The graphics are also a huge step up from the original, with smooth colours and intricately designed animation elements.
How the Spins Work: Rules and Features at a Glance
This slot is played on a grid made up of 5 reels and 3 rows and has, as we previously mentioned, no traditional paylines, but instead works with 243 ways to land a win, based on simply collecting adjacent symbols. The highest paying icon is the game logo (which also doubles as the Wild) with a 1,000 payout, followed by gods Thor and Odin, rewarding 500 and 450, respectively. The Wild symbol substitutes all icons except for the Bonus and also doubles all winning paylines it’s a part of. Related to the this is also the Wildstorm feature, in which lighting randomly turns reels into Wilds. A new feature highlighted just after loading Thunderstruck II offers paytable rewards which you achieve when you complete all payout combinations for a particular symbol.

Other electrifying element of this slot is the Bonus symbol which grants you entry to the Great Hall of Spins when you collect 3, 4 or 5 of them. In the Great Hall, you can enjoy the Valkyrie Bonus – 10 free spins with a 5x multiplier, but it doesn’t end there. If you’ve triggered the bonus featured 5 times, you move on to the Loki Bonus, with 15 spins and a Wild Magic symbol that randomly changes icons into substitutes. The next two bonus levels are that of Odin and Thor, triggered by the 10th and the 15th bonus activation, respectively. The Odin bonus rewards you with 20 free spins during which black ravens turn symbols into multipliers up to 6x. Finally, Thor’s bonus offers 25 spins with a Rolling Reels feature, giving you an increasing multiplier with each consecutive win (up to 5x).
