When the original Thunderstruck title was first released back in May, 2004, the software house Microgaming arguably set a new standard in slot gaming graphics and gameplay.
Far from resting on their laurels, however, this developer created the stunning sequel Thunderstruck II exactly six years later in the spring of 2010.
This title is certainly visually impressive, whilst the high-quality audio and animation also contribute to a genuinely immersive gameplay experience. The high-value, Nordic God symbols (namely Loki, Odin, Thor and Valkyrie) are also beautifully designed, whilst Thor’s Hammers also makes for an iconic bonus icon!
Borrowing heavily from the theme and Norse mythology that underpinned the original, this superb slot has certainly managed to remain true to its roots, whilst offering enhanced gameplay, a stunning 5×3 reel grid and a whopping 243 ways to win!
The latter point is particularly important, as it means that Thunderstruck II eschews fixed paylines and instead operates a system in which all symbols serve as adjacent scatters. So, winning combinations can be forged when matching icons land anywhere on adjacent reels, creating a higher proportion of base game wins and a return-to-player (RTP) rate of 96.65%.
Despite its competitive RTP rate, this mid to high-variance slot also offers a potentially huge jackpot during the Wildstorm feature, with up to 2.4 million coins on offer if all five reels are transformed into wilds at this time.
Altogether, there’s no doubt that Thunderstuck II is an improvement on the original slot, which was already a cult classic in the eyes of players.
The sequel is also one of the most enduringly popular titles of all-time, and it remains a staple of online casino platforms throughout the UK, Europe and beyond.

If you’re a fan of the original Thunderstruck slot, you may be tempted to jump straight in and start playing the sequel straight away!
However, it’s important to note that these are two mechanically very different games. The sequel is a 243-payline slot whereas the first game has 9 fixed betways and less winning combinations.
The good news is that you’ll still be able to toggle between different coin values in order to determine your total stake per spin, although you won’t have the option to choose how many paylines you’d like to activate.
Instead, you’ll start by choosing a coin value of between 0.01 and 0.05, before selecting a fixed number of coins to stake (between one and 10).
These decisions create a betting range of between £0.30 and £15 and, whilst this may seem a little small in comparison to some slots, it’s important to remember that there are some healthy multipliers on offer during the base game and bonus rounds.
The Thunderstruck II logo is the game’s wild symbol and pays out at 1,000-times your stake in instances where you land five on adjacent reels, for example, meaning that you can bank a maximum of 15,000 coins during the base game alone!
On a final note, it’s also important to remember that this slot boasts a ‘Bet Max’ feature at the bottom of the screen.
This automatically optimises your stake amount ahead of every single spin, and we’d recommend that you utilise this during lucrative bonus rounds and when the biggest multipliers are on offer (we’ll have a little more on this below!).
Thunderstruck 2 Feature 1 – Wildstorm
Whilst there are some slots that boast a larger number of bonus rounds, Thunderstruck II has focused primarily on quality over quantity.
This is definitely evident when you unlock the aptly-named Wildstorm feature, which leads to a deceptively lucrative period of gameplay that supports the game’s main bonus round!
The Wildstorm bonus can be triggered randomly during the base game and revolves around the iconic Thunderstruck II logo wild symbol.
This symbol can substitute for almost all other icons on the five reels to forge new and unexpected winning combinations.
Keep in mind though that the logo ceases to be wild during the Wildstorm bonus round, as once this has been triggered, you’ll notice a significant on-screen transformation take place. More specifically, at least one of the five reels will turn completely wild at this time, creating potentially huge winning combinations and massive multipliers.
During this bonus, it’s also possible for all five of the game’s reels to turn completely wild, and it’s at this time that the top prize of 2.4 million coins is available so long as you’ve staked the maximum amount.
Thunderstruck Feature 2 – The Great Hall Of Spins
We’ve already touched on the role of Thor’s Hammer, which is the slot’s scatter symbols and can unlock the coveted Great Hall of Spins.
In fact, landing three or more of the scatters across the five reels will kick start this bonus round, which is home to four distinct features that have been built around each of the four, high-paying Nordic Gold symbols.
So, here’s a breakdown of the four free spin features and a little insight into how and when they’ll be triggered:
- Valkyrie: One of the most famous female Gods in Norse mythology, the Valkyrie bonus round is the first to unlock in the Great Hall of Spins. This is triggered just as soon as you land three or more of the Thor’s Hammer scatters for the first time, whilst you’ll instantly be rewarded with 10 free spins and in-game multipliers of five-times your stake.
- Loki: Loki is another popular Norse God, and his bonus feature will be unlocked on the fifth trigger of the Great Hall of Spins. This will award players with 15 free spins, whilst unlocking the ‘Wild Magic’ symbol that can randomly transform other icons into wilds when it lands on reel three. You can also earn up to four additional free spins if the bonus is retriggered!
- Odin: The famous God Odin becomes available on the 10th trigger of the free spins bonus, at which stage players will earn 20 free spins and unlock the so-called ‘Wild Raven’ feature. The raven will turn symbols into two or three-times multipliers at random, whilst landing two simultaneously will trigger a multiplier of six-times your stake.
- Thor: The Great Hall of Spins feature closes when you trigger the thunder god Thor, who becomes available on the 15th round of this stage. You earn 25 free spins whilst unlocking a ‘Rolling Reels’ feature, with the latter awarding multiple consecutive wins and maximum multipliers of five-times your stake!
Once all of the Gods have been unlocked, you’ll have the autonomy to choose your favourite one the next time you trigger the Great Hall of Spins feature.
This is a huge boon, and there’s no doubt that you can rake in some huge wins once you’ve triggered the Great Hall of Spins feature for the very first time.
Despite the differences between fixed payline slots and those with 243 (or more) ways to win, the most important technical aspect of gameplay is the bet limits in place.
After all, winnings in 243-payline slots are calculated as multipliers of your initial stake, so the amount that you wager will have a direct impact on the value of individual winning combinations.
There’s also a relatively wide betting range on offer to players, who can wager a minimum of £0.30 and a maximum of £15 during the base game and bonus rounds.
OK, we hear you ask, but how exactly do these betting limits impact on my potential returns? Of course, this partially depends on the value of the winning combinations that you land, but the slot’s paytable enables you to quickly calculate the multipliers associated with different symbols.
For example, let’s say that you land five of the iconic Thor symbols on adjacent reels. This will payout at a multiplier of 500-times your stake, meaning that players who stake the minimum of £0.30 will bank a total of £150 in purely financial terms.
Conversely, high-rollers who stake the maximum of £15 per spin will boost their bankroll considerably with this winning combination, landing a lucrative cash prize of £7,500.
Whilst neither of these prizes are negligible, we can see the direct influence that your stake amount has on the value of various winning combinations.
However, it’s important to remain within your financial means at all times, so don’t be afraid to stake smaller amounts in order to make your bankroll go further (particularly with some of the base game and bonus round multipliers on offer).

This leads us neatly on the maximum win, which varies depending on the precise stage of the game that you’re in.
If we take the base game as an example, you’ll see that landing five of the Thunderstruck II wild symbols on adjacent reels offers the highest multiplier of 1,000-times your stake. So, at the maximum stake of £15 your spin, you could bank a cool £15,000 with a single winning combination.
The value of winning combinations in the Great Hall of Spins will vary wildly, however, depending on the feature that you’ve unlocked and the multipliers that are in play.
The slot’s biggest win is reserved for the aforementioned Wildstorm feature, however, with a staggering 2.4 million coins on offer in instances where all five of the game’s reels turn wild simultaneously.
Thunderstruck 2 On Mobile
Thunderstruck II is now more than nine years’ old, and yet, despite this, the game’s graphics have remained relevant in the digital age.
This slot has also benefitted from several software updates during the last few years, the last of which was rolled out in 2018.
This ensured that the game was powered by Flash and HTML5 technology, enabling players to access it seamlessly through both desktop and mobile browsers.
So, regardless of whether you’re accessing an instant play casino or a native app on Android or iOS, you’ll be able to play Thunderstuck II in top quality.
Our Xpert Review
Fans of modern slots may consider Thunderstruck II to be a little outdated, as, despite regular software updates, the graphics are not as crisp as some players would like.
However, this should not distract you from the high-quality gameplay on offer here that makes this an immersive slot that has built a large cult following over the course of the last decade.
Whether you’re enjoying the base game or benefitting from five-times multipliers in iconic Great Hall of Spins, Thunderstruck II is an exceptional slot game that manages to combine a competitive RTP rate with a maximum payout of 2.4 million coins!
This makes for a compelling game with an enduringly popular theme that brings excitement, mystique and energy in equal measure.
Ultimately, whilst there may be more modern and eye-catching slots on offer in the iGaming market, few can match the depth and status of Microgaming’s Thunderstruck II. In fact, we can’t be alone in hoping that we see a Thunderstruck III unveiled at some point in the future!
