Thunderstruck II Mega Moolah Online Slot Review

Legendary Norse gods star in the Thunderstruck II Mega Moolah slot machine from Games Global. It’s part of a hugely popular series and while this version retains everything that made the others so successful, this time the gods bring a huge progressive jackpot feature with them.

Play the Thunderstruck II Mega Moolah slot on a PC, iOS, Android, or Windows mobile and unlock a series of free spins bonus features from Odin, Loki, Valkyrie, and Thor. You can also benefit from stacked wilds across the reels, and if you trigger the progressive jackpot feature, a win is guaranteed.

It’s a 5-reel game with 243 ways to win, a high volatility, and average returns of 92.01%. Prizes from the main game can hit 8,000x your stake, but the biggest of the 4 progressive jackpots has been known to award over 20,000,000.00 at the online casinos!

How to Play the Thunderstruck II Mega Moolah Online Slot

A blue / grey stone effect dominates the backdrop, although there’s a detailed Norse style decorative frame to the 5x3 symbol grid. Metallic playing card symbols feature here, alongside the slightly cartoonish images of Thor, Odin, Loki, and Valkyrie, plus a longship, Asgard, and bonus symbols such as the game logo and hammer of Thor.

The current progressive jackpots are on display to one side of the reels, with the straightforward controls to the other. Click a stack of coins on the panel and you can select from a bet range of 0.30 to 24.00 per spin. You play with 30 coins and win from enough examples of the same symbol type, or wild, across adjacent reels from the left. The 3 small lines on the controls take you to the paytable, where you see how much you can win from the various symbols.

If you want to sit back and watch the reels spin on their own, tap the circular arrows button and activate Autoplay mode (where allowed). The lightning bolt button speeds everything up, so you don’t have to wait for the reels to come to a stop before you find out if it’s a winning spin or not.

Free Spins & Other Bonus Features of the Thunderstruck II Mega Moolah Slot Machine

The game logo is a wild symbol that can step in to complete or improve a win by acting as others. Any win involving the wild is doubled in value, and Thor can strike the reels at random times to unlock a Wild Storm feature. From 1 to all 5 reels then fill with staked wild symbols, with a win of 8,000x the stake coming your way if it fills the whole grid.

If 2, 3, 4 or 5 hammer scatter symbols stop in view on the same spin, you get an instant prize of 1x, 2x, 20x or 200x the bet. Any 3 or more hammers also unlock the Great Hall of Spins free games feature. There are 4 levels of free spins, which unlock gradually as follows –

Valkyrie Spins – 10 free games with a 5x multiplier. Retrigger this round for 10 further spins.

Loki Spins – Available from 5th trigger. 15 spins where wilds transform other symbols into further wilds. More scatters award 4 extra spins.

Odin Spins – Available from 10th trigger. 20 spins where a Wild Raven feature turns symbols into multiplier wilds of 2x, 3x, or 6x.

Thor Spins. Available from 15th trigger. 25 spins where a Rolling Reels system removes winning symbols and new ones drop down to replace them. Rolls continue for as long as they form new winning combinations and a multiplier increases by 1x, to a maximum of 5x, on each Roll.

Look to the side of the reels on your PC or mobile where you see the current progressive jackpot values. The jackpots increase as a small percentage of stakes made across the Mega Moolah slot network is set aside until players scoop the prize and they reset, ready for another win.

Mini, Minor, Major, and Mega jackpots start at 10.00, 100.00, 10,000.00, and 2,000,000.00 respectively. Collect coins on the middle reels to increase the chance of entry to the round and once it begins you simply spin a colourful bonus wheel to see which jackpot you win.

Outside the progressive prizes, the biggest win from the Thunderstruck II Mega Moolah slot is 8,000x the stake, or 192,000.00 at the highest stake. This is a high volatility game, and like many progressive slots, it comes with lower than usual average returns, in this case, just 92.01%.

Our Thunderstruck II Mega Moolah Slot Rating

The low return to players percentage is the big hammer in the works. If you want to go for a potentially vast progressive prize, the Mega Moolah jackpot is perhaps the biggest out there, but if you want better returns, then Thunderstruck II has all of the same features, minus the jackpots.

Stacked wilds and the 4-stage free spins are certainly exciting, so whichever game you play, the Norse gods can bring plenty of wins to you at our approved slots uk casinos.
