Thunderstruck II Gameplay

Thunderstruck II, released by Microgaming in 2010, offers an engaging gaming experience with its Greek mythology theme, 243 paylines, and the potential to win up to 2,000x your bet. The game features 5 reels and 3 rows, with a minimum bet of $0.30 and a maximum bet of $15. Players are captivated by its medium volatility and a Return to Player (RTP) rate of 96.65%.

To play Thunderstruck II, start by setting your bet amount between $0.30 and $15. Spin the reels to match symbols from left to right, starting with the leftmost reel. The game’s wild symbol, represented by the Thunderstruck II logo, substitutes for all symbols except the scatter and doubles any win it contributes to. The scatter symbol, depicted by Thor’s hammer, pays in any position and is key to unlocking the Great Hall of Spins.

Landing three or more scatter symbols triggers the Great Hall of Spins, offering four unique free spins features that unlock sequentially. The Valkyrie feature awards 10 free spins with a 5x multiplier on all wins and can be retriggered. The Loki feature grants 15 free spins with the Wild Magic feature, transforming up to 15 symbols into wilds. Odin’s feature gives 20 free spins with the Wild Raven feature, where ravens can turn symbols wild and apply up to a 6x multiplier. Thor’s feature, unlocked after 15 entries, provides 25 free spins with Rolling Reels™, increasing multipliers up to 5x for consecutive wins.

Thunderstruck II’s Wildstorm feature randomly turns up to five reels wild, enhancing win potential. The game’s high-value symbols include Thor, Odin, Loki, and Valkyrie, while low-value symbols are represented by traditional card values.

Our Review


Thunderstruck II impresses with its 243 paylines and varied bonus features like the Great Hall of Spins. The medium volatility and a high RTP of 96.65% make it suitable for many players. The game’s graphics and sound design enhance its Greek mythology theme, adding to the immersive experience. This earns it 4.5 out of 5 rating. However, the absence of a progressive jackpot limits potential big wins. Additionally, the maximum bet of $15 per spin may not appeal to high rollers. Introducing higher betting limits and a progressive jackpot feature could enhance the gaming experience further. Overall, Thunderstruck II remains a top choice for slot enthusiasts.
