Thunderstruck II Game Play Overview
Thunderstruck II surrounds you with dramatic, HD visuals and smooth 3D animations inspired by Norse mythology. Its cinematic soundtrack enhances the epic vibe, while every win triggers striking audio cues. You will find performance seamless on both iOS and Android, with responsive controls and crisp graphics. The actual RTP is 96.65%, which is slightly above average, giving you a fair shot over time. This is a high volatility slot, so you might hit dry spells but can land thrilling big wins—especially when the Wildstorm feature turns all reels wild for maximum payout.
How to Play Thunderstruck II
Thunderstruck II uses a 5-reel, 3-row grid and a 243 ways to win system. All ways are always active, letting you form combinations on every spin.
Choose Your Bet

Thunderstruck II Features and Bonuses
Thunderstruck II offers a rich suite of bonus features, making every session exciting. Explore the main bonuses and special mechanics below.
Wilds
The Thunderstruck II Logo acts as the wild symbol. It substitutes for all symbols except scatters and doubles any win it completes. Wilds appear on every reel.
Scatters
Mjolnir, Thor’s Hammer, serves as the scatter. Land three or more anywhere to trigger the Great Hall of Spins bonus. Scatters also award payouts up to 200x your stake.
Great Hall of Spins (Free Spins)
Triggered by landing three or more scatters, this feature unlocks four unique free spin rounds: Valkyrie, Loki, Odin, and Thor, each with their own bonuses and modifiers.
Valkyrie Free Spins
Awards 10 free spins with a 5x multiplier on all wins. Valkyrie is available from your first trigger and can be retriggered by landing more scatters during the round.
Loki Free Spins
Unlocks after five bonus triggers. You get 15 free spins, and the Wild Magic feature on reel 3 can randomly transform other symbols into wilds. Extra free spins can also be won.
Odin Free Spins
Available after ten bonus triggers. This round gives 20 free spins plus the Wild Raven feature, which randomly adds 2x or 3x multipliers to wins, with both ravens combining for 6x.
Thor Free Spins
Unlocked after fifteen bonus entries. You receive 25 free spins. The Rolling Reels mechanic increases your win multiplier by up to 5x with consecutive wins in a single spin.
Wildstorm Feature
This randomly triggered bonus can turn up to all five reels wild in the base game, creating massive win potential in just a single spin.
Multipliers
Multipliers appear in multiple features: 5x in Valkyrie spins, 2x/3x/6x via Odin’s Ravens, and up to 5x through Rolling Reels in Thor’s round, boosting your total payouts.
Paytable Achievements
Complete all payouts for each symbol to unlock achievements. As you do, the paytable turns gold for that symbol, tracking your progress and adding an extra layer of challenge.
Bonus Buy
Thunderstruck II does not offer a Bonus Buy feature. All bonuses must be triggered during regular play.
Feature Evaluation
The features in Thunderstruck II remain impressive and innovative, even years after release. The multi-level free spins and Wildstorm are unique, offering far more than standard slot bonuses. These mechanics set a benchmark and still stand out against newer industry releases.
