Thunderstruck II slot review

Thunderstruck II slot from Microgaming is a 2010 sequel to the original Thunderstruck game that was released 6 years prior. Both games are based on Nordic Mythology and feature the gods like Thor, Odin, Loki and Valkyrie. The second instalment became a proper cult and made it to the list of the top played slots ever mostly thanks to the lucrative and elaborate The Great Hall of Spins feature. In this review, we’ll check the game’s features closely and see which of the UK online casinos will let you play it, while providing you with a sweet casino bonus.

Thunderstruck II slot features and free spins

Thunderstruck II slots is set on 5 reels and 243 ways to win with the symbols of the four main gods as well as card symbols carved from the rock. The game logo acts as a Wild symbol to substitute all the other symbols apart from the Scatter, which is a Thor’s Hammer.

The main attraction of Thunderstruck II slot is without any doubt the multi-level The Great Hall of Spins feature. To trigger it initially you will have to land at least 3 of the Thor’s Hammer scatters. The way the free spins levels work is the following:

Level 1 - Valkyrie

The first four triggers are the Valkyrie level, which comes with 10 free spins and a x5 multiplier. It is possible to retrigger more free spins during this level.

Level 2 – Loki

The second Loki level will keep going from the 5th until the 9th triggers. Here you receive 15 free spins with an addition of the Wild Magic feature, which starts on the middle reel and transforms the normal symbols into more wilds.

Level 3 - Odin

The third level runs through the 10th - 14th triggers and awards you with 20 free spins and an extra Wild Raven feature. One of Ravens will give you either x2 or x3 multiplier. Get 2 Ravens and receive x6 multiplier applied to all your wins.

Level 4 - Thor

Starting from the 15th trigger, you can benefit from the final Thor Free Spins level. Here players enjoy 25 free spins and the extra Rolling Reels feature. The more consecutive wins you get in a row, the bigger the multiplier you get. It starts from x2 and goes up to x5.

After you’ve gone through the Thor’s feature, you will be able to start picking and choosing the free spins level yourself.
