MÁQUINAS DE JOGO
Thunderstruck II is a slot game from the Games Global catalogue, with a historical origin in Microgaming. It is a classic of the Thunderstruck series: a 5x3 grid, 243 ways, a verified RTP of 96.65% and a volatility listed as Medium in the technical data consulted.
The game remains well-known for its Great Hall of Spins, its four free spins modes linked to Valkyrie, Loki, Odin and Thor, and its random Wild Storm bonus. It should therefore be viewed as an older progressive bonus slot, rather than a modern feature buy release.

Great Hall of Spins
The main bonus is triggered by 3 or more scatters. The game then grants access to the Great Hall of Spins, which acts as a progression between four modes. Valkyrie is available from the start with 10 free spins and a 5x multiplier. Loki is unlocked after several activations and adds wild transformations on reel 3.
Odin brings 20 free spins with the Wild Raven feature, which can turn symbols into multipliers. Thor is the most advanced mode: 25 free spins, Rolling Reels and a progressive multiplier up to 5x. This progression explains why Thunderstruck II holds a special place in the series.
Wild Storm
Wild Storm can trigger randomly during the base game. Up to 5 reels can turn wild, which radically changes the value of a spin. It is an old feature, but it remains the game's real highlight because it can transform an ordinary grid into a much more valuable spin.
Points of caution
Thunderstruck II does not have the pace of a modern slot. It can feel quiet between bonus triggers, especially if progress through the Great Hall is slow. Its volatility is listed as medium, but the real interest remains concentrated on Wild Storm and the free spins modes.
The verified RTP is 96.65%. Before playing for real money, you should still open the casino's information screen: some operators may offer a different RTP variant, betting limits or availability depending on the market.
Our quick opinion
Thunderstruck II is worth playing primarily for its status as a classic. The 243 ways remain simple to understand, the four bonuses provide a real structure, and Wild Storm still holds great promise. On the other hand, players looking for a highly modern, fast-paced or feature-buy-oriented slot will probably prefer the more recent sequels.
To stay within the saga, compare it with Thunderstruck Stormchaser and Thunderstruck Wild Lightning. For another Games Global title already released, take a look at Treasure Tracks.
