Thunderstruck 2: Mega Moolah Slot RTP, Details & Wager Limits

Reels/Paylines: 5 reels + 243ways to win

Stakes Range: 30p to £24 per spin

Max Win: 8,000 x stake per spin

RTP: 93.38%

The Thunderstruck 2: Mega Moolah slot is played on 5 reels, 3 rows and 243 ways to win. A winning combination is formed when 3 or more matching symbols appear from left to right on adjacent reels beginning from reel 1. The symbols can appear on any position on each reel.

Stakes range from 30p to £24 per spin. Click on the ‘Coins’ icon to bring up 6 available bet levels. There’s also a slider which you can see you choose a specific stake. Outside of the UK, you will see a lightning bolt icon which brings the Quick Spin mode into play. There’s also an Auto Play function where up to 100 autospins can be selected. Both these options are not available in the UK.

Unlike the non-jackpot version, the volatility is in the medium category. The hit frequency rate is 32.74% meaning nearly a third of spins on average will give you a winning combination/outcome.

The Thunderstruck 2: Mega Moolah RTP is 93.38%. 5.3% of that return is reserved for the progressive jackpots though. In the non-jackpot version, the RTP is very high at 96.65%.

When it comes to payouts, the maximum win per spin is 8,000 x your total stake. This can be won from the Loki Free Spins or Wildstorm features. You can win a lot more from the 4 progressive jackpots (more details below).

Theme – join Thor again in Asgard

Theme: Norse Mythology

High Value Symbol: Thor

Compatibility: Mobile, Tablet, Desktop


The Thunderstruck 2: Mega Moolah slot is inspired by Thunderstruck 2, one of Microgaming’s most popular slot games ever. Set in Asgard and with a Norse mythology theme, the graphics and soundtrack are identical to the classic game that was originally released in 2010. It has since been revamped as late as December 2020.

With a blue background, you will instantly be hit with the soundtrack which is epic and could feature in a Hollywood film or Netflix series. Based on the Norse god of thunder, Thor, the visuals are a little dated but that doesn’t matter in my opinion as it’s a cult classic.

Symbols include low value A, K, Q, J, 10 and 9 royals. Then you have viking longships, Asgard and gods Valkyrie, Loki, Odin and Thor. Thor is the best paying symbol with 3, 4 or 5 in combination awarding 1, 3.33 or 16.67 x your total stake.

Then you have the Thunderstruck 2 wild symbol which replaces all symbols bar the scatter. 3, 4 or 5 wilds will also pay 2.5, 6.67 or 33.33 x stake. Importantly, your win is doubled when a wild substitutes. The scatter is represented by the Thor’s Hammer bonus symbol.

Thunderstruck 2: Mega Moolah Mobile


Produced using HTML5 technology, Thunderstruck 2: Mega Moolah is available to play on mobile, desktop and tablet devices. The 5×3 setup works just as well on an iPhone or Android device that on a laptop or PC. For the best experience, a bigger screen is always better in my personal opinion.

Thunderstruck 2: Mega Moolah Bonus Features

The Thunderstruck 2: Mega Moolah slot has 9 bonus features. There are random wild reels and 4 free spins features with various extras. Then you have the jackpot element with 4 progressive jackpots to be won randomly.

Wild Storm feature

In the base game, there is a Wildstorm feature that is randomly activated. Thor strikes the reels with lightning bolts and changes between 1 and 5 reels into wild reels. 5 wild reels will pay 8,000 x your total stake.

The Great Hall of Spins features


Like in the original slot, The Great Hall of Spins features are the main attraction. This is triggering by landing 3 or more Thor’s Hammer bonus scatters. 2, 3, 4 or 5 scatters will award, 1, 2, 20 or 200 x stake respectively.

Trigger the Great Hall of Spins 5, 10 or 15 times to play the other free spins features

With 4 free spins features, you will begin with access to the Valkyrie Free Spins feature. To play the other features, you need to activate The Great Hall of Spins features 5, 10 and 15 times. Here are all the details:

Valkyrie Free Spins feature: always available, you’ll be rewarded with 10 free spins and a 5x multiplier. You can win an additional 10 free spins giving you 20 in total.

Loki Free Spins feature: available from the 5th trigger, you begin with 15 free spins. There’s a Wild Magic feature which is played when Wild Magic symbols appear on the middle reel. They randomly transform symbols into additional wilds. 2, 3, 4 or 5 scatters will give you 1, 2, 3 or 4 extra free spins.

Odin Free Spins feature: available from the 10th trigger, you’ll play 20 free spins. There’s a Wild Raven feature which is triggered when Odin’s Raven symbols appear. They transform symbols into 2x and/or 3x multiplier. Land 2 ravens to get a 6x multiplier.

Thor Free Spins feature: available from the 15th trigger, you get 25 free spins. There’s a Rolling Reels feature where sees the multiplier increase by 1 with each win. Successive wins can lead to a 5x multiplier.

Jackpot Bonus feature


Finally, this game is part of the Mega Moolah series. This means you can win 4 progressive jackpots. The Jackpot Bonus feature is activated randomly on any spin. You get to spin a wheel which will reward you with 1 of the jackpots.

The Mega Jackpot is the biggest of the progressive jackpots and begins at £1 million. The real-time jackpot is £3,126,062.89. Here’s what each jackpot will pay out as a minimum (seed value):

Jackpot Seed Value
Mini Starts at £10
Minor Starts at £100
Major Starts at £10,000
Mega Starts at £1 million

The Mega Jackpot has also paid a world-record €19.4 million in April 2021. It pays out over £3 million every 65 days on average. The latest jackpot winner came in February 2022 and was €7,296,286.88.

Bonus Features

RTP (93.38%)

Max Win (8,000 x)


The Thunderstruck 2: Mega Moolah slot is essentially Thunderstruck 2 with 4 progressive jackpots. There’s no doubt this game will appeal to players who love the original game and chase life-chasing jackpots. Microgaming did the same with Immortal Romance: Mega Moolah.

In terms of the gameplay, it’s identical to the original slot with the 4 free spins features being the main attraction. The randomly triggered Wildstorm feature in the base game can give you 5 wild reels and 8,000 x stake max wins. Of the free spins features, the Loki Free Spins feature is potentially the most lucrative and can pay the top amount.

It would be have ideal to have an extra feature but this may upset fans of the original game. It’s literally a way that Microgaming can introduce jackpots to lovers of Thunderstruck 2. Big Time Gaming has done the same with Megapays versions of Bonanza Megaways, Who Wants to be a Millionaire Megapays and Star Clusters Megaclusters.

If the jackpots are something that don’t appeal to you, the original game is much better with a significantly higher RTP (96.65% vs 93.38%).

I do prefer Immortal Romance to Thunderstruck 2 personally as it offers higher max wins (12,150 x stake vs 8,000 x stake). This is also offered in Immortal Romance: Mega Moolah.

If it’s jackpots you’re after though, check out our jackpot slots section which has all the Mega Moolah series games as well as other titles from NetEnt, Playtech and Big Time Gaming.
