Thor and Loki are causing havoc in the sequel to the classic slot, Thunderstruck. Almost 10 years after its predecessor, Thunderstruck II has also managed to become a modern classic, and here’s why.

Introduction to Thunderstruck 2

If there’s a slot machine that could be considered a true slot classic, it’s Thunderstruck and its sequel, Thunderstruck II. The original was released as early as 2003 and achieved great success in the gaming world, so much so that this sequel was released 7 years later.

This slot review is about the sequel, Thunderstruck II. Like the original, Thunderstruck II is inspired by Nordic mythology. The design comes in various shades of blue and is undoubtedly inspired by the cold Nordic winter. Of course, you also get to meet familiar Nordic gods and symbols inspired by the Vikings.

Thunderstruck II’s variance (or volatility) is medium. Online slots with medium volatility give neither particularly large nor particularly small winnings, but are something that suits players who like a perfect balance between these two. The RTP (return to player) is 96.65%, which is acceptable in our casino reviews. We like numbers at least 95%, but if the RTP exceeds 96%, it’s even better.

Features in Thunderstruck 2

There’s nothing groundbreaking about the gameplay format in Thunderstruck II. You have 5 reels, 3 rows, and 243 ways to win, which is very common in the gaming world. The various Nordic gods and the game’s logo are the slot’s highest paying symbols, and they can give you the following winnings:

There are 14 standard symbols on the reels, so Microgaming has definitely worked hard on this impressive amount. In addition to the different god symbols, there’s also a Viking ship and the card symbols 9, 10, J, Q, K, and A.

The highest possible win in the base game in Thunderstruck II is 2.4 million coins. You get this if you bet 10 coins per spin and manage to get the game’s logo on all 15 positions on the reels. If you play with the highest possible coin value, this means a win of $120,000.

Free spins mode

Thor’s hammer functions as the scatter symbol in this slot machine and is responsible for starting the slot’s free spins mode. The free spins mode in this slot changes depending on how many times you’ve managed to start it. Here’s the table of the different free spins modes and their attributes:


It’s been almost 20 years since Thunderstruck was released and about 10 years since Thunderstruck II was released. Both of these slot machines continue to be relevant and popular among players. The many different free spins modes that change the longer you play keep the slot interesting, while the different possibilities for multipliers make the gameplay very fun.

The design is sleek, meaning it’s detailed without being overdone. The symbols are nice, although some players complain that they pay too little. The slot has also received complaints that the variance seems much larger than what Microgaming says it is. We don’t take a stand on this, but it’s good to be aware of these complaints.

It’s worth noting that Thunderstruck II is available at many online casinos with a UKGC license, making it a safe and reliable choice for UK players. Additionally, the game is available to play on both desktop and mobile devices, so you can enjoy the slot wherever and whenever you want.

Overall, we highly recommend Thunderstruck II to players looking for an exciting and engaging online slot experience. With its attractive design, numerous features, and decent payouts, Thunderstruck II is a slot that’s definitely worth checking out.
