Microgaming's epic Norse mythology slot — four legendary bonus tiers, 243 ways to win, and the might of Thor, Odin, Valkyrie, and Loki at your command.
Thunderstruck II is Microgaming's definitive Norse mythology slot and the worthy sequel to the original Thunderstruck — itself one of the most popular slots of its era. Released in 2010, the game draws from the rich tapestry of Viking legend, bringing Thor, Odin, the Valkyrie, and the trickster god Loki to life with stunning illustrated artwork, dramatic lightning effects, and a thunderous soundtrack that makes every big win feel genuinely epic. It remains one of the most visually impressive and mechanically rewarding slots Microgaming has ever produced.
Like Immortal Romance, Thunderstruck II uses a 243 ways-to-win system on a 5x3 grid, ensuring that winning combinations form naturally without the constraint of fixed paylines. The 96.65% RTP and medium volatility position it perfectly for players who want a blend of regular engagement and high-ceiling bonus potential. The Great Hall of Spins — a four-tier bonus structure unlocked progressively — gives the game extraordinary replay value, with each new tier revealing more powerful and more lucrative bonus mechanics the more you trigger the free spins feature.
Great Hall of Spins — 4 Bonus Tiers: The centrepiece of Thunderstruck II is the Great Hall of Spins, unlocked when three or more Scatter symbols appear. Four distinct bonus rooms are revealed progressively as you accumulate free spins triggers. The Valkyrie room (first unlock) awards 10 free spins with a 5x multiplier. Loki's room gives 15 free spins with a Wild Magic feature that adds extra wild symbols. Odin's room grants 20 free spins where Odin's ravens can transform low-value symbols into high-value ones. Thor's room — the pinnacle, unlocked after 10 free spins triggers — delivers 25 free spins with a Rolling Reels mechanic that builds multipliers up to 5x on consecutive wins.
Wildstorm Feature: At random during the base game, a lightning bolt can strike the reels and trigger the Wildstorm feature. When it activates, between one and five reels can turn completely wild for that spin, producing potentially massive payouts from a single base-game spin. The unpredictability of Wildstorm keeps every spin charged with anticipation.
243 Ways to Win: The ways-to-win system means three or more matching symbols on consecutive reels from left to right count as a win regardless of their row position. With high-value symbols depicting Thor, Odin, the Valkyrie, and Loki, the upper end of the paytable pays extremely well when multiple ways to win are triggered simultaneously.
Thunderstruck II's progressive bonus structure means it genuinely rewards loyal play — each free spins trigger brings you closer to the extraordinary power of Thor's 25-spin Rolling Reels room, which represents some of the best bonus potential Microgaming has ever engineered into a single game.
