If you’re an avid slot fan, you’ve surely heard about Microgaming’s two biggest hits – Thunderstruck II and Mega Moolah. The first is a legendary slot based on Norse mythology with electrifying features, while the second is the world’s top progressive jackpot slot. These slots have immense popularity, and years after their release, Microgaming decided to blend them into a single game.

When they hit the market, both slots had fun features on offer. They’re back for another run in this slot simply titled Thunderstruck II Mega Moolah. It’s essentially another Norse adventure with Odin and Thor, except this time it has a Mega Moolah jackpot attached to it.

The slot’s a medium variance affair with an unusually low RTP of 92.01%. That’s because of the massive progressive jackpot that’s floating as high in the sky as Asgard. The slot combines the best elements from both worlds – it has 243 ways to win and the Great Hall of Spins feature while offering four progressive jackpots worth a lot of money.

Thunderstruck II Mega Moolah follows the aesthetics and vibes set by its predecessor. The 5x3 reels are set against a stone wall background, with famous characters from Norse mythology on them. You’ll see the Allfather Odin with a patch, Thor himself, his famous hammer Mjolnir, and a Valkyrie. These are the premiums that pay up to 20x, while the Scatter Mjolnir and Thunderstruck II Wild pay the most – 240x and 40x respectively for five.

A soothing soundtrack with crackling lightning sound effects in the background is a nice touch. The slot looks as great as you expect it, and is a pitch-perfect copy of the original.

The Thunderstruck II Mega Moolah was produced on the HTML5 platform. It is available on Android and iOS devices via mobile browsers, no app download is required.

Choose a bet from $0.30 to $24 per spin and hit the Spin button on the right to start the game. Any wild that’s part of a win doubles it – that’s one of the greatest features in the Thunderstruck II Mega Moolah base game.

The Wildstorm feature strikes randomly and can turn up to 5 reels fully Wild. Due to its winning potential, the Free Spins Round can’t be triggered during this feature. Being a medium variance slot, you can expect these features to hit frequently, but not too frequently. The great surprise in the Thunderstruck II Mega Moolah slot is the four progressive jackpots.

These are won randomly too, but the higher your bet, the better your chance to hit them. Unlike in the original Mega Moolah slot, in this one, you’ll need to collect Progressive Trigger Coins to win the respective jackpot. When the feature hits randomly, you get a spin on the Jackpot Wheel. These network jackpots are incredible, with the largest one, Mega, seeding at $1,000,000.

The wheel will stop on one of the four jackpots and award the win instantly. On average, a Mega Moolah jackpot drops every 8 weeks, and with millions of players spinning these slots, the awards can grow pretty big.

The Great Hall of Spins feature is triggered by three or more scattered Mjolnirs. There are four Free Spins Features unlocked progressively with subsequent retriggers.

• Valkyrie: 10 free spins from the first trigger with x5 multipliers.
• Loki: 15 free spins from the fifth retrigger with the Wild Magic feature that transforms up to 15 symbols randomly when the special symbol lands on the reels.
• Odin: 20 free spins from the tenth retrigger with Wild Ravens. Odin’s ravens can transform up to 2 symbols to Wilds and award an x2 or x3 multiplier. Both multipliers can combine for x6 Wilds.
• Thor: 25 free spins from the fifteenth retrigger with Rolling Reels and multipliers up to x5 for consecutive Rolls.

The RTP of the Thunderstruck II Mega Moolah slot is only 92.01%, but keep in mind that it’s full of special features and four progressive jackpots. The regular maximum win not counting the jackpots is 8,000x the stake.

Microgaming has managed to perfectly pair two of its most popular slots into a single progressive jackpot-headed beast. It’s a worthy sequel to both Thunderstruck II and Mega Moolah, pairing the best of both worlds and creating a world of its own. One that we would like very much to live in, mind you. With the great winning potential aside from the jackpots, this is a slot no player should miss at top online casinos.
