Thunderstruck II

Thunderstruck II takes you back on a mythological journey to Valhalla, inspired by Norse gods and epic battles. As a sequel to the Microgaming original, this slot expands on its predecessor with enhanced visuals, immersive storytelling, and entertaining gameplay features. 

As you spin the reels of the Thunderstruck II slot, you will, once again, be face-to-face with Thor, Loki, Odin, and Valkyrie. Other symbols include Viking ships and mythical artefacts, all intricately designed and complemented by a cinematic soundtrack that brings the Norse mythology theme to life. 

With an RTP of 92.05% and high volatility, Thunderstruck II offers plenty of entertainment and unexpected twists. The slot works seamlessly on mobile devices and is almost entirely automatic, so once the reels are in motion, you can sit back and watch the result unfold. 

Enter the God’s Realm 

Like most online slots by Microgaming and other leading software providers, Thunderstruck II features a simple and intuitive interface. To get started, simply set your stake by clicking the coins icon. Then Press the spin button to launch your first set of reels. 

Winning combinations in Thunderstruck II form whenever three or more matching symbols land on adjacent reels. There are no paylines on the 5x3 grid and row positions don’t matter, however, every eligible formation must start from Reel 1. As a result, there are 243 ways to win per spin. 

There are 12 standard symbols in the game, four of which are the slot’s main characters. Landing five Thor symbols across the grid pays 16.67x while the maximum payout from Odin symbols is 15x. Loki, meanwhile, pays a maximum of 13.33x and Valkyrie’s maximum prize is 11.67x. 

The slot’s logo symbol is wild and substitutes standard symbols to complete or grow winning combinations. When a wild symbol forms part of a winning formation, it doubles the standard payout. In addition, wilds pay between 2.5x and 33.33x whenever three or more form a suitable winning combination. 

Thunderstruck II Features 

Thunderstruck II includes various features designed to enhance gameplay and introduce different mechanics inspired by Norse mythology. Each feature adds a unique element to the gaming experience, adding depth and variation to each spin. 

Wildstorm Feature 

The Thunderstruck II Wildstorm Feature can trigger on any spin, transforming up to five reels wild. Free spins cannot be triggered during the feature and reels stay wild for a single spin. 

Thunderstruck II Free Spins 

Like most slot games at our online casino, free spins in Thunderstruck II are triggered by three or more scatters. However, unlike most online slots, four types of bonuses can be unlocked. Triggering free spins multiple times unlocks more types. 

With the first free spins trigger, you play the Valkyrie Free Spins bonus, consisting of 10 free spins where all wins are multiplied by 5x. Moreover, free spins can be retriggered with three or more scatters. 

From the fifth free spins trigger, you can play the Loki Free Spins bonus where Wild Magic symbols appear on Reel 3. Whenever this symbol hits, it transforms up to 15 symbols into Wild Magic symbols. In addition, free spins can retrigger with two or more scatters. 

On the 10th bonus trigger, Odin Free Spins become available. This bonus begins with 20 free spins where Odin’s Ravens can transform up to two symbols wild. These symbols can boost winning combinations they are part of by up to 3x, but if two Ravens land, boosts can climb to 6x. 

Thor Free Spins become available with the 15th bonus trigger, activating the Rolling Reels mechanic that replaces winning combinations with new ones. Every time this mechanic is activated, it increases the base stake multiplier, up to a maximum of 5x.
