Thunderstruck Slot Review

Thunderstruck Slot is a Nordic-themed slot from Microgaming! This review will give you all the insight you need to know about this slot.

The game takes after the Norse mythology theme of Thor and his escapades. The game has gained so much popularity over the years, and it has earned itself cult status and is one of the internet’s most popular slot games. Thanks to the free spins feature, it offers big wins, where you can win up to 30 free spins with a 6x multiplier.

To form a win, you need to land 3, 4 or 5 matching symbols across a payline, beginning from reel 1. All matching combinations pay from left to right. The symbols pay pretty well, and in the case of a wild symbol, you only need to land 2 on the reels of a slot.
