You can play the Microgaming-powered Thunderstruck II video slot at Mr Green Casino – find out how to get up to £250 free when you join.
Thunderstruck II is a cult classic as it’s become one of the most popular online slots. Launched in May 2010, it has 5 reels and 243 ways to win and has a Norse mythology theme (this means you will see Nordic gods like Valkyrie, Thor and Odin). What makes this game so good is the bonus features.
In the base game, you have the Wildstorm feature which is randomly triggered. You will get 1 re-spin with up to 5 reels turning completely wild. I’ve managed to get 3 wild reels a few times which has resulted in some of biggest wins to date on this game.
The main attraction is The Great Hall of Spins feature which is triggered by obtaining 3 or more Bonus Hammer symbols anywhere on the reels. This is a 4 level bonus feature where you can reach the other levels by triggering the feature a certain amount of times. The Valkyrie feature is the first you will be able to access and here you get 10 free spins with a 5x multiplier with the possibility to get more free spins.
My favourite though is the Thor feature which you can access once you trigger the feature 15 times or more. You receive 25 free spins with Rolling Reels meaning that consecutive wins increase the multiplier between 2x and 5x. That said, The Great Hall of Spins feature has a memory so you can pick up where you left off.
