The maximum exposure per spin is 8,100 times your total bet. This can be won from the random Wildstorm feature in the base game and from a free spin in the Loki Free Spins feature.

Thunderstruck 2’ RTP

The Thunderstruck 2 slot RTP rate is 96.65%. This is on the higher end for an online slot (generally about 96%) with a house edge of just 3.35%. Couple that with the low variance mechanic and this game should see your balance last a relatively long time.

Thunderstruck 2’ Audiovisuals

The Thunderstruck 2 slot takes its inspiration from the Norse God of Thunder, Thor. The hammer-wielding god features in many online slots such as Playtech’s Age of the Gods.

The visuals are quite basic as it has a rather plain blue backdrop. The first thing you’ll notice is the distinct soundtrack which is majestic-like. You’ll see A, K, Q, J, 10 and 9 royals on the reels as well as Thor (the mighty god of thunder), Odin (ruler of Asgard), Loki (god of mischief) and Valkyrie (maiden of Valhalla). Thor is obviously the highest paying symbol paying out up to 16.67 x your stake for 5 in a winning combination.

The Thunderstruck 2 logo is the wild symbol and doubles your win when part of a win with other symbols. It also offers much bigger payouts than the Thor symbol with up to 33.33 x your stake for 5 in a row.

Thunderstruck 2 isn’t as sharp aesthetically as other online slots as it was released in 2010. However, it has a live casino feel to it and enhanced the playing experience. Saying that it can be played across a wide variety of devices including those powered by iOS, Android and Windows operating systems. This means you can play on desktop, mobile and tablet devices.

Here, you will choose from 4 free spins features, each one based on a Norse god. However, the Valkyrie Free Spins feature is always available whilst the other 3 can be chosen once you enter The Great Hall of Spins a certain number of times. There is a progress bar to help to keep count.
