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.
