Thunderstruck Wild Lightning Slot, is it better than Thunderstruck 2?

Thunderstruck Wild Lightning Slot Logo

The highly anticipated sequel to the amazing Thunderstruck II slot has arrived!

Casumo Casino has recently added the new Thunderstruck Wild Lightning Slot to their casino, published by Microgaming. This is an iconic slot that has been developed by Stormcraft Studios being pitched as the sequel to the successful Thunderstruck II video slot, which is a BIG claim!

Certainly, the production value is high on this slot release with realistic 3D graphics and new innovative game mechanics along with original game music that even has its own Spotify Playlist.

It has been many years since the original Thunderstruck and Thunderstruck 2 slots were released. Both were extremely popular in their day, and a lot has changed in the online slot world in terms of what attracts players, so making a new slot in this iconic series live up to the hype is always going to be a tough task to fulfil.

We want a mix of nostalgia reminding us of the predecessors and some fresh new features and huge win capabilities that modern slots offer, but retaining that certain style the original slot has.

Thunderstruck Slot Overview

In Thunderstruck Wild Lightning, we again “Join Thor the new ascended ruler of Asgard, on an epic quest to retrieve the lost World Stones”.

The slot has done away with the old 243-way payline structure and opted for a 5×4 reel layout using 40 fixed paylines.

In addition, in the base game, we now have Multiplier Wilds with 2x and 5x values randomly being applied to wins,  helping to produce some nice base game hits that keep the gameplay interesting.

Thor’s Mighty Hammer is the Scatter symbol and remains in the game. Landing 3 Scatter symbols signal the start of your adventure into one of the 5 unique free spins rounds. The more volatile free spin bonus rounds must be unlocked just like in the original Thunderstruck II slot by triggering the bonus feature multiple times.

Stake size can be configured from as little as £0.20 up to a maximum bet of £16, and there are various sliders for coin sizes and amounts, giving you great customisation of bet sizes.

The new Thunderstruck has been optimised for both desktop and mobile gameplay. The slot is fully responsive, with all key features being repositioned perfectly for mobile play.

Link & Win Feature

A new addition to the base game is the electric blue Thunderball symbols which are part of the LINK & WIN feature. In essence, it’s a simple re-spin mechanic bonus feature with cash prizes, but this can also can trigger a variety of stake based jackpots that go up to a staggering 15,000x!

You start with 3 Re-Spins, landing any further Thunderballs resets this spin counter. If you manage to collect enough of these symbols, further tiers unlock, giving you additional spaces to land more Thunderballs. Fill this board up completely, and you are looking at a Mega Jackpot win!

Wildstorm Feature

The iconic Wildstorm Feature has been altered in this release to be a collection based unlock. Rather than occurring randomly in the base game, you now need to fill up a Wildstrom Meter (20 x 2 Scatters) before this Wild Reel mechanic becomes available as a Free Spins Bonus option (more detail on how this works later!)

The good news is that 5 Full Wild Reels is still a possibility on this slot, however rare it may be to trigger the good news is that it is still possible!

Base Game

The base gameplay uses a 5×4 reel set with 40 fixed paylines, along with the usual high and low paying symbols there are Thor Wilds which can add multipliers to wins in the range of 2x up to 5x.

Free Spins Modes

Thunderstruck Wild Lightning Mobile Slot - 2x Multiplier Wilds
Thunderstruck Wild Lightning Mobile Slot - Free Spins Round

5 unique free spins bonuses are unlockable on this slot. The first time you trigger the bonus feature, only one option will be on offer. Further bonus triggers are required to unlock each new free spin option. 5 further bonus triggers are required each time to unlock each new option.

The later free spins modes offer a much more volatile style with fewer starting spins, bigger multipliers and, as a result, way more volatility.

The Wildstorm being the 5th option is unlocked from the base game but resets once this option has been selected and played, forcing you to refill the meter again before being able to select it again.

Final Thoughts on Thunderstruck Wild Lightning

So it Better? We didn’t think so, but they definitely had a good go trying!

Being a successor to any slot such as Thunderstruck 2 or Immortal Romance is almost an impossible task. They are probably the most iconic Microgaming slots ever produced.

While Thunderstruck Wild Lightning has certainly made a good attempt at injecting a fresh take on the classic, it has a number of shortfalls. The change from a 243-way payline system seems unnecessary, and we would have preferred a super high variance 243-way incarnation of the machine.

The extra bonus features, whilst good in their own rights, felt to us like they detracted from the core gameplay that made Thunderstruck 2 so good, a lot is going on with so many mini-features, and it feels like the slots RTP has been spread thinly over these additional features, sure you won’t be complaining if you do hit a 15,000x Jackpot, but the main bonus rounds felt a bit diluted because of this.

The collection Meter for the Wildstorm feature doesn’t seem like an improvement either. The excitement of the original versions was you never knew when it was coming until the base game rumbled and lightning crackled over the reels began. The current revision seems like a drawn-out process of collecting “failed bonus triggers” for a very risky bonus feature that actually requires you to trigger it as a bonus too before you actually get to play it!

That all said, it does have many positives, the sheer amount of polish regarding the sound, graphics and animations, which are all top-notch.

The free spins round mechanics are great too once triggered, and a nice twist on the originals with multiplier wilds and full wild reels being added thanks to the Wild Lightning Feature. Overall it’s worth a look as long as you don’t set your expectations of this sequel too high!
