How do you play the Thunderstruck II slot game?

Whenever someone talks about slots with gods, two common mythology games come to mind: Age of the Gods slot (Greek mythology) and Thunderstruck (Norse mythology). The Norse mythology games are one of our favourites, and everyone enjoys the games for the stacked in-game mechanics, including multiple bonus games and modifiers.

If you have enjoyed Thunderstruck, then the sequel is just as fun, maybe even better. Whether you want to call it Thunderstruck 2 or Thunderstruck II, the popular slot game from Games Global is a must-play title for any Norse mythology fan. Thunderstruck II is played on a 5×3 grid, with 243 paylines, a max win of over 8,000x and an RTP of 96.65%. While Thunderstruck II may not fit in with today’s crowd of games with vibrant animations and fast-paced disco beats, the game has a smooth display and the graphics and sound give off a nice old-school vibe.

Similar to other Games Global partnered titles like the 9 Pots of Gold slot game, you can play the Thunderstruck II slot game for fun and real money. If you want to play for fun, click the demo option on this page to learn the game mechanics and rules.

Below is a step-by-step guide on how to play the Thunderstruck 2 slot game:

  1. Whether you are playing Thunderstruck II slot free play on this page or for real money at online casinos, once the game loads, the first thing to do is read the game info.
  2. Afterwards, you should set your coin and bet size using the +/- tool on the game’s homepage.

Explaining the symbols in the Thunderstruck 2 slot game

Similar to White Rabbit slot, Thunderstruck II has several game symbols, including low-paying and high-paying symbols. You must land three or more symbols along adjacent reels to get a winning combination. As long as you land three or more matching symbols from left to right across adjacent reels, you will get a winning combination, irrespective of the position of the reels.

As is common with most slot games, such as the White Rabbit Megaways slot, Thunderstruck II has special bonus symbols. The game logo is the Wild symbol and appears throughout the game, and substitutes for all other symbols. The scatter symbol is the Thor hammer, Mjolnir, which triggers the bonus round games if you land three or more scatter symbols (more on that soon).

Below is a breakdown of the Thunderstruck II slot game symbols:

Thunderstruck II slot highlights

Thunderstruck II stands out for the bonus features, and we liked that there are bonus features for both the base game and feature games. One of the highlights is the base game Wild Storm bonus feature. The feature can trigger for any base game spin, and once triggered, up to five reels will be made into special Wild reels, and the max win is over 8,000x should you get five expanding Wilds.

If you land three or more scatter symbols, you will trigger the Great Hall of Spins feature. There are four free spin feature modes which unlock sequentially. Each time you trigger the Great Hall of Spins feature, you will unlock a new bonus game feature with a special character and an in-game modifier.

Below is a brief breakdown of the four different Great Hall of Spins features:

  • Valkyrie – 10 free spins and all wins have a 5x multiplier.
  • Loki – 15 free spins and a Wild Magic modifier.
  • Odin – 20 free spins and a Wild Raven modifier.
  • Thor – 25 free spins and a Rolling Reels feature.

Can you play Thunderstruck 2 on mobile?

Thunderstruck 2 is available on mobile, and you can play on the go from anywhere and at any time. Depending on the real money online casino you use, your available mobile gaming options include playing on a mobile app or with the mobile-optimised website. Regardless of the mobile gaming options, the gameplay should be the same as when playing on a desktop. We loved the mobile gameplay experiences, and despite playing on a smaller screen, the game fits nicely on both Android and iPhone devices, and you can tailor the gameplay to your specs, including using the autoplay function.

A word of advice: Ensure you are playing through WiFi or have a stable internet connection when using your mobile data. By doing so, you can have a seamless Thunderstruck II mobile gaming experience, without any annoying lags or buffering between spins.

Conclusion – Thunderstruck II is a must for all slot fanatics!

Generally, whenever there is a sequel to something, it fails to live up to the first instalment. However, that is not the case with Thunderstruck II, and we believe gameplay is just as good, maybe even better than the OG Thunderstruck title. The gameplay is simple, the bonuses are exciting, and you can also play on the go. What more can you ask for!

However, don’t forget that it can take a little while to learn the mechanics, especially the different bonus game modes, so please read the game info first. If you want to play for fun and test the game out, you can play the demo mode on this page. Alternatively, click the relevant banners on this page to play for real money at the top online casinos.
