The reels have the traditional layout and use of standard 9 – Ace symbols, with additional images of the Norse Gods and Asgard. At any point during the main game, the ‘Wild Storm’ feature can be randomly triggered.

The game features a Player Achievements structure, making sure that previously unlocked features can be resumed in new play sessions. The scatter symbol in the form of Thor’s hammer – Mjölnir – awards entry into The Great Hall of Spins and each entry to this feature will bring you closer to unlocking the chambers of the other gods, who wield greater features and rewards. The more bonuses you win, the more bonuses you can win!

In the Free Spin games you can receive a multiplier up to six times (6x) and also the chance to get even more Free Spins in the same bonus round.

But the gods of Thunderstruck II go even further in offering new features, such as the randomly triggered ‘Wild Storm’ feature which can turn up to five reels wild. The introduction of a Player Achievements structure allows you to track your progress and pick up where you left off last session.
