Overview
Thunderstruck II is one of Microgaming’s most popular video slot creations. It was released in 2010 as a sequel to the original Thunderstruck, and like that game it is based on famous characters from Nordic mythology, such as Thor, Odin and Loki.
Thunderstruck II gained its fame due to its bold theme and comprehensive set of bonus features, which we’ll cover in more detail below, alongside everything else you need to know about this game.

SPECIAL FEATURES
Gameplay and Features
The game’s biggest attribute is its massive winning potential, which is spread across several special features.
In the base game you should be anticipating the Wild symbol (the Thunderstruck II logo), as it substitutes for all other symbols (except for the Scatter) and doubles your win. Three or more Scatter symbols will activate The Great Hall of Spins, which is split into four bonus games, each carrying unique merits of its own.
- Valkyrie Bonus Game: 10 Free Spins with a constant X5 multiplier.
- Loki Bonus Game: 15 Free Spins with the Wild Magic feature, which randomly awards additional substituting symbols.
- Odin Bonus Game: 20 Free Spins with the Wild Raven feature, where ravens will randomly turn symbols into multipliers up to X6.
- Thor Bonus Game: 25 Free Spins with the Rolling Reels feature, increasing your multiplier by up to X5.
When you trigger the bonus round, you’ll be able to select the Valkyrie Bonus Game, with the rest progressively unlocked via Scatter Symbols. Lastly, Thunderstruck II hosts the vanishingly rare Wildstorm feature, which randomly strikes your reels and can potentially turn all symbols into Wilds, paving the way for a massive win.
Thunderstruck 2 offers a max payout of 2,500,000 coins if you un-lock and win all the multi-level free spins bonus features.
Graphics and Sound
Thunderstruck II delivers a great representation of the mythic characters it’s based on, the most notable aspect of it being the absorbing soundtrack that will accompany you throughout gameplay.
The graphics are right in line with other Microgaming titles, but they won’t dazzle you too much, which isn’t surprising considering its age. On the flipside, you’ll find that Microgaming has done a great job with the animations and occasional crackling thunder noises appearing on winning spins, which aid greatly in immersing you into the game.
Review Summary
Thunderstruck II excels in both of the important aspects of video slots; aesthetics and winning potential. The Nordic mythology theme is a favorite to many, and features like The Great Hall of Spins and even The Wildstorm feature have the potential to multiply your stake to incredible heights.
As with most Microgaming slot releases, this game skews towards the high-variance side, meaning that its great rewards will come at a greater investment of your bankroll. If you feel that its playstyle matches your taste, then Thunderstruck II is one of our top recommendations.
