About Thunderstruck 2 Slot

Thunderstruck II is a sequel to the popular Thunderstruck slot that was released a decade ago. However, the popularity of the revamped Thunderstruck 2 slot increased so much that it earned the reputation of being the best online slot! This new sequel comes with improved graphics, exciting features, and big wins.

The Thunderstruck II slot plays on 5 reels, 3 rows, and 243 active paylines. Before spinning the Thunderstruck 2 slot’s reels to try and land winning combinations on any of the 243 paylines, you must select your bet per spin. Betting options range between £0.30 and £15 per spin, and you can choose your preferred bet by using the + and - buttons at the bottom of the screen.

How do you win big in Thunderstruck 2?

Like most online slots, you will win big in Thunderstruck 2 by landing winning combinations of three or more symbols on any of the active paylines. As all 243 ways to win are fixed, all you’ll need to do is choose your bet and start spinning.

Landed combinations of five symbols, meaning one of each on each reel, will reward you with the highest payout. Thor is the most lucrative of all, paying out an impressive 500x your coin size for a combination of five across a payline.

The Thunderstruck 2 slot is able to have so many paylines and ways to win because it pays out for combinations landed on adjacent reels both left to right and right to left! The maximum payout you can win here is capped at 8,000x the stake, and it can be won through the bonus features.

What is the main character of the Thunderstruck slot series called?

The main character in this epic tale is Thor, the Norse god of thunder/ lightning. You’ll play with him, as well as with other popular Norse gods who will help you trigger the free spins and win the maximum payouts.

Design, Symbols and Graphics

Upon launching Microgaming’s Thunderstruck II slot, you’ll instantly notice the incredible and somewhat icy-looking graphics. The steel blue background and border barely separates themselves from the reels and the chiselled playing card symbols!

Thunderstruck II lives up to expectations after an impressive and exciting predecessor. The graphics are crisp and accurate, whilst the extra bonus features are sure to keep players enticed. Overall, it's nicely designed and the gameplay is smooth, whilst the 243 ways to win keep excitement levels high!

We think the Thunderstruck 2 graphics are the key part of this slot and contribute to the quality of the game. The gods are extremely well-drawn and even the playing card symbols are on-theme, designed in an icy, rocky style, as they perhaps should be with a Nordic-themed slot.

This slot also features some nice animations, including the lightning flashes both on and above the reels, for instance when the scatter symbols are landed. Plus, the reels spin smoothly and players don’t have to wait too long for them to stop, hopefully landing on some high-paying combinations.

The symbols also help to boast of the game's aesthetic quality, with the likes of a Viking longship and Norse gods Loki, Valkyrie, Odin and Thor all taking place on the reels, alongside the 9, 10, J, Q, K and A.

Aside from the standard reel symbols, this slot’s wild is represented by the Thunderstruck II logo and will substitute for all others to help create winning combinations, except the hammer scatter.

RTP, Variance and Payouts of Thunderstruck 2 Slot

Thunderstruck II slot is a highly volatile game, which means that rewards can be less frequent, but proportionately more valuable at the same time. The maximum possible win in this game reaches up to 8,000x the stake.

The Thunderstruck 2 slot RTP is capped at 96.55%, which is a great value above the industry average. The hit frequency is 32.62%, so, on average, a third of the spins will result in winning combinations.

Gameplay and Features on Thunderstruck 2 Slot

Like the first one, Thunderstruck 2 has plenty of exciting bonus features to keep players enticed and to keep the wins coming, or at least the chance of them!

Wildstorm Feature

This feature can occur randomly. When triggered, up to five reels will turn completely wild and players are then given the chance to land some lucrative combinations.

The Great Hall of Spins Feature 

This is perhaps the Thunderstruck II slot’s main bonus feature and one that triggers more frequently and gets more profitable the longer you play. Landing three or more of Thor’s Hammer symbols will trigger this round with the gods and their respective rewards.

How many free spins features are there in the Great Hall of Spins in Thunderstruck II?

There are 4 different free spins features that you can trigger in the Great Hall of Spins. There is a progress bar to show you how many features you’ve unlocked. Here’s what you can win:

  • Valkyrie Free Spins - available from the first retrigger. It gives you 10 free spins with a 5x multiplier;
  • Loki Free Spins - available from the 5th retrigger. It gives you 15 free spins and the Wild Magic feature. Look out for Wild Magic symbols that can land on reel 3, as they transform random symbols into wilds;
  • Odin Free Spins - available from the 10th retrigger. It gives you 20 free spins and the Wild Raven feature. The Wild Raven feature randomly transform symbols into 2x and 3x multipliers;
  • Thor Free Spins - available from the 15th retrigger. It gives you 25 free spins with the Rolling Reels feature. When you land a win, the multiplier increase by 2x. Subsequent wins will increase the multiplier up to 5x the stake.

Better yet, during the Thunderstruck II Great Hall of Spins bonus feature, free spins can be re-triggered, so this round has the potential to be extremely lucratively again and again!
