How Thunderstruck II plays
Five reels, three rows, 243 ways, and a Norse cast. Thor is the wild and doubles any win he completes. Three or more Mjölnir hammer scatters open the Great Hall of Spins, which is the heart of the game: four free-spin rooms that unlock in order the more often you trigger the hall. Valkyrie gives ten spins at 5x. Loki adds a wild-reel feature, Odin adds ravens that multiply wins, and Thor brings rolling reels with a multiplier that rises through a cascade. Your progress through the rooms is stored with your casino account, so a returning player can pick a room a newcomer cannot.
In the base game, Wildstorm can trigger at random and turn up to five reels fully wild.
Volatility in practice
High. Base-game wins are modest until Wildstorm hits, and the free-spin rooms vary widely: Valkyrie is steady, Thor is where the big rolling-reel wins happen. The 8,000x maximum needs Wildstorm or a long Thor cascade.
RTP settings
96.65% is the highest published setting. Games Global, which now owns the Microgaming catalogue, offers lower settings to operators, and a lower setting applies to the whole game, including the Great Hall. Check the info panel for the setting your casino runs.
