This game is a great sequel to the very popular Thunderstruck slot games series. Powered by Microgaming and released in 2010, Thunderstruck 2 builds upon the beautiful aspects of the original Thunderstruck slot machine to establish one of the fascinating iGaming experiences on Easy Slots Casino.

Thunderstruck 2 RTP is 96.65%, and its volatility at high levels. This means that the house edge for this game is 3.35%, while the wins might come less often but higher in terms of size; this is also illustrated through the 8,000x fixed jackpot prize available in this online slot.

Free spins, wilds, scatters, multipliers, and cascading wheels are all at play in Thunderstruck 2, complemented by 243 ways to win and a 5x3 gameplay. We recommend this Mythology-based slot to all punters looking to try something original and classic.

Overview of Thunderstruck 2 Slot Game

If you happened to play an online slot by the name of Thunderstruck and found yourself itching for more, then we have some good news for you. Microgaming, the online developers that have been instrumental in the industry, creating lasting experiences that last an entire lifetime, have finally created a much-anticipated sequel to Thunderstruck; that plays to all of the strengths of the first instalment with additional features that give a somewhat different experience to things.

Thunderstruck slot release had an RTP of 96.50%, but the Microgaming sequel that we review here is 0.15% higher. It is rare to see classic software providers releasing slot games with so high RTP, which makes Thunderstruck 2 a worthwhile online slot. Nonetheless, the most important element of this game is the high variance. This statistic affects the gameplay from the first spin, unlike the RTP, which illustrates the long-term payouts.

As with most ways to win slots, the Thunderstruck 2 slot has high volatility, suggesting less frequent payouts but very lucrative ones. The bet levels range from $0.30 up to $15, so it is likely to spend quite a few bucks until you start seeing returns. Nonetheless, if the reel spins towards your pocket, you could see up to $120k being added to your bankroll - all thanks to the multiple, dynamic Thunderstruck II slot bonus game.

How to Play Thunderstruck 2 Online Slot

The appropriately titled Thunderstruck 2 is a five-reel slot with a lot of personality and flare. Like with the first instalment in the franchise, you can expect wilds, scatters, free games, among added features that all push this sequel into the territory of a great follow-up to a pre-existing title. But let's not jump ahead of ourselves. Firstly, let us walk you through the process required to play Thunderstruck 2 slot:

  1. As there are no traditional paylines but 243 ways to win instead, players will only have to set their bet levels. These range from $0.30/$15 per spin, and players can adjust according to their circumstances through the Coin button, located at the left of the spin button.
  2. Then, there is the autoplay function, which allows you to set several spins to take place automatically and the turbo button, which decreases the animation time.
  3. Following the above two steps, players can hit the centre button to spin the reels for a real money wager. Nonetheless, there is also another function available, whereby players can find further details into the values of each symbol.
  4. In every round, players must match a minimum of 3 identical symbols on adjacent reels to win the corresponding multiplier.
  5. Wilds help form winning combinations easier, as they substitute all other symbols except the scatters. The latter pay even if only two land on the reels.

Game Graphics

It is reasonable for Thunderstruck 2 players to expect some difference from the original game; here, you only need to look at the graphics to spot it. As with the official Microgaming title of the same name, players follow the adventures of Thor as he battles other Gods on the road to Valhalla. Nonetheless, the sound effects, animations, and imagery are on a whole different level - establishing a much more pleasing experience.

Still, Thunderstruck II slot is not as advanced as other slots released by Microgaming in 2021, but they offer a decent level of detail. The good news for players is that this online slot is instantly accessible on any device, offering an equally pleasing experience.

Symbols in this Slot

Like in the first Thunderstruck, a series of symbols cascade across a table of pure lightning. Expect anything and everything related to Thor once again serving as the symbols; we find that briefly mentioning what to expect with the symbols is better than just outright stating what they are. Personal experience trumps spoilers any day of the week. Different symbols will open different avenues for success depending on the symbol and how many are involved in the winning pay-line of a successful spin.

Symbols in the game include the letters and cards, coloured in a metal fashion to fit the background - which pay the lowest prices. The high paying symbols include Mjolnir, Loki, Valhalla, Thor, a Viking ship, Valkyrie, and Odin. Each pays a respective multiplier, as follows:

Thunderstruck II Symbols

2x symbols anywhere on the reels

3x symbols on adjacent reels

4x symbols on adjacent reels

5x symbols on adjacent reels

Viking Longship








































Thunderstruck 2 Free Spins & Great Hall of Spins Feature

Overall, this is one of the richest online slots in terms of bonuses, so we explain each to help you understand each before you start spinning the reels for real money.

Wildstorm Feature

Players can enjoy a single bonus feature in the base game, namely, the Wild Storm feature. It is activated at random, transforming anywhere between 1 - 5 reels into wilds. The maximum win of 8,000x your bet in Thunderstruck 2 can originate from 5 wild reels.

Special Symbols: Wilds & Scatters

The Thunderstruck wild symbol in this game is the logo. It substitutes for all other symbols, while it also carries great value itself; 3x wild symbols pay 2.5x, 4x wild symbols pay 6.66x, and 5x payout 33.33x the bet size.

The only symbol that is not substituted by the wild symbol is the hammer Scatter symbol. The Mjolnir represents it and pays out the following values:

  • 2 Mjolnirs - 1x
  • 3 Mjolnirs - 2x
  • 4 Mjolnirs - 20x
  • 5 Mjolnirs - 200x

If three or more scatters land anywhere on the reels, players unlock the Great Hall of Spins, the bonus game featured around the main game characters. Free Spins, Rolling Reels, Wild Magic Feature, Wild Raven and other special spins bonus games await you there.
