In Norse mythology, Thor’s chariot is pulled by two rams: Tanngrisnir and Tanngnjostr. The legends say that Thor killed and ate the rams to gain sustenance from their flesh, before using his hammer to resurrect them.
The two goats and the hammer play an important role in the Thunderstruck slot. The goats act as the game’s Scatter symbol, triggering an instant win when 2 to 5 are revealed and 15 free spins with 3 to 5. As for the hammer, it rewards some of the biggest payouts and is second only to the Wild.
During the free spins, all wins are tripled, making the wild and the Mjollnir Hammer even more powerful. The spins will also trigger again if three or more scatters appear on the reels when it is active.
SOFTWARE AND MOBILE EXPERIENCE
Thunderstruck hit the market four years before the first iPhone was released. The developers couldn’t have known how popular mobile gaming would have become, or even if it would be a thing, and so the early iterations of Thunderstruck weren’t mobile-ready.
A lot has changed since then, though, and the Thunderstruck slot game now looks great on mobile. It’s fast, smooth, and simple. And the fact that it’s an old-school slot that’s not weighed down by big graphics and features means that you can enjoy it even on older devices.
