Thunderstruck II RTP and Wagering

This popular online video slot was developed by Microgaming back in 2010. Although it is quite an old game it is still popular among slot players because of all the great bonus features included in the game. It features a 5x3 reel layout with 243 ways to win. The game is set in a mystical world of Norse mythology, with symbols such as Thor's Hammer, Valkyries, and Odin. The wagering range allows players to bet from as low as £0.30 per spin up to a maximum of £15 per spin. The coin value per spin ranges from £0.01 to £0.05.

The maximum possible win is up to 8000x your bet. To trigger the maximum win of your stake you must land five Thunderstruck II logo symbols on an active payline during the Wildstorm feature or Loki Free Spin. The game has a long-term Return to Player (RTP) rate of 96.65%, which is considered to be slightly higher than the average RTP for online video slots. However, you need to keep in mind that this is a theoretical percentage based on very complex calculations and does not guarantee that you will get back that amount.

Thunderstruck II Bonus Features

Thunderstruck II’s popularity definitely stems from the different bonus games within the game.

Here I will go through each bonus game and explain how to trigger them and what they can offer the player.

The Great Hall of Spins 

The Great Hall of Spins is Thunderstruck II's main bonus feature. This bonus game is triggered by landing three or more scatter symbols anywhere on the reels. Players can unlock four different levels of free spins in this feature, each with unique features and payouts. The more you trigger the Great Hall of Spins, the higher your chances of unlocking the higher levels. This is very similar to the free spins levels within Immortal Romance. There is also a progress bar which clearly shows you which level you have achieved so far.

Loki Free Spins

The Loki Free Spins feature is the second level of the Great Hall of Spins and is unlocked after triggering the Great Hall of Spins five times.In this feature, players get 15 free spins with an added bonus symbol called the Wild Magic symbol. If this symbol lands on reel 3 it will randomly turn other symbols on the reels into wilds. The max possible win within this bonus game is up to 8,000x your bet.

Odin Free Spins

The Odin Free Spins feature in Thunderstruck II is the third level of the Great Hall of Spins. It is unlocked after triggering the Great Hall of Spins 10 times. In this feature, players are awarded 20 free spins, with a unique Wild Raven symbol that can randomly turn other symbols on the reels into 2x or 3x multipliers.

Thor Free Spins

The Thor Free Spins feature is the final level of the Great Hall of Spins. Players can unlock this level after triggering the Great Hall of Spins 15 times. This feature awards 25 free spins to players along with the Rolling Reels feature. This boosts the multiplier on each consecutive win up to 5x. 

Wildstorm Bonus Feature

The Wildstorm Feature on Thunderstruck II is randomly triggered during gameplay. It can turn up to five reels completely wild, broadening your chances of landing a lucrative winning combination. If you manage to land 5 wild reels you can win up to 8,000x your bet.
