Whether you're looking to play for free in demo mode to test strategies or seeking the best casinos to play for real money, we've got you covered.

Thunderstruck II's Gameplay and Mechanics

In Thunderstruck II gameplay and mechanics, you'll dive into the world of Norse mythology across 5 reels and 3 rows. The game's symbols reflect the rich theme, featuring Thor, Asgaard fortress, lightning bolts, and Thor's mighty hammer. If you're a fan of free online casino slot games, this one is a must-try.

Thor himself acts as the Wild Symbol, doubling wins when substituting for other symbols and landing 5 Thor symbols on a payline rewards you with a maximum payout of 10,000 coins. Look for the scatter symbol (2 rams) to trigger the Free Spins bonus, offering cash prizes and 15 free spins.

During Free Spins, enjoy a fantastic x3 multiplier, and the Thor Multiplier means a thrilling x6 payout for each winning wild combination. Plus, you can restart the free spins with 3 or more scatters, keeping the excitement going!

When comparing this game with other Thunderstruck games, it has a higher RTP but with a slightly old layout that needs a bit of modification.

Thunderstruck II Features: Unlocking Epic Rewards

In Thunderstruck II, you'll encounter a plethora of thrilling features that can lead to massive wins:

  • Thor's Hammer — this symbol, despite its low value, is crucial. Collect at least 3 to enter the Hall of Spins, where various characters grant free spins, mini-games, and win multipliers.

  • Valkyrie — landing this symbol in the Hall of Spins triggers 10 free spins with an x5 multiplier for your wins.

  • Loki — unlock Loki on your fifth bonus game trigger, and enjoy 15 free spins with the Wild Magic Feature. This feature can transform symbols into additional Wilds, enhancing your chances.

  • Thor  the main character, Thor, appears on your 15th entry to the Spins Room. He rewards you with Rolling Reels, a win multiplier, and the ability to turn the main symbol into a Wild.

  • Game Logo — this symbol acts as the Wild, replacing all others except for Thor's Hammer. Combinations with it grant free spins and activate a double multiplier.

  • Wildstorm Feature — this electrifying feature can appear on any base game spin, turning up to 5 reels completely wild. Achieving this is a path to stunning wins, with a potential payout of 8,100X your stake.

  • Great Hall of Spins — this feature offers four varieties with different rewards and modifiers, starting with Valkyrie free spins. It unlocks sequentially, triggered by bonus rounds. Valkyrie's round, Loki's transformation, Odin's multipliers, and Thor's Rolling Reels offer distinct advantages.

With Thunderstruck II's impressive array of features, the possibilities for big wins are endless compared to when playing any other Thunderstruck game like Mega Moolah. It's an epic journey through Norse mythology filled with rewards, excitement, and legendary gameplay.

Our First 100 Spins of Thunderstruck II in the demo

I started my first 100 spins of Thunderstruck II in a demo with a balance of 1,000 coins. Placing bets in this game is straightforward, with a minimum of $0.30 and a maximum of $15 per spin. However, something happened on the 30th turn wherein I got 3 Thor's Hammers that took me to the hall of spins.

My demo play started bearing bonuses when Valkyrie offered me ten free spins and 5X my stake on the 40th spin. The demo also revealed significant wins since, after a spin of 100, I was left with 968 coins.

Your success in the game involves studying its symbols in the paytable and features. Look out for Thor's hammer, as well as that for the Hall of Spins, for the chance to get huge wins. While going through this journey, experience the thrill of the game and brace yourself for spectacular victories.
