Thunderstruck II Slot: Join the Norse Gods in Slots' History

  • The Thunderstruck Slots franchise is one of the most successful products ever created by Microgaming
  • The first Thunderstruck game launched in 2004 with an RTP of 95.1%
  • The Thunderstruck II Slot followed in May 2010 with an increased RTP of 96.65%

The Thunderstruck series is, to Slots and gambling, what Nintendo's first GameBoy is to gambling or what the 1994 FIFA video game has been to countless breakups.

Not only it is the game we all played back then. It is the game we all wanted to play. I am sure you get the difference.

When the Thunderstruck Slot hit the world of online Casinos, online gambling changed forever. When the Thunderstruck II game came about six years later, an evergreen classic was born.

Theme and Symbols

Let's start from the basics and explore the theme of the Thunderstruck II Slots.

If you think Vikings Slots and games based on Norse mythology are a new trend started by Irish-Canadian co-production Vikings TV series, you are wrong.

The original Thunderstruck and Thunderstruck II Slots pioneered the genre bringing troops of brave Scandinavian heroes to our screen when Michael Hirst was still busy exploring the history of the United Kingdom.

These are the games that brought to the screen Odin, Loki, Thor, the road to Valhalla, and even the Valkyries.

Dancing on the reels at the sound of a truly epic soundtrack, these symbols help you build winning combinations, trigger bonus rounds, and set the background for heroic missions in the cold North.

The gaming experience one gets while playing Thunderstruck II is not something many Slots can offer. And so are the wins, as this mid-variance game comes with a top win of 2,400,000 credits.

Since not everyone will be lucky enough to walk away 2,400,000 credits richer, here's the complete breakdown of all the winning combinations (and their respective payout) of the Thunderstruck II online Slot game.

The random symbols payout of this non progressive slots

The Thunderstruck logo is the wild symbol. Not only it helps you build winning combinations, but it also comes with an added 2x that multiplies everything you win through it.

The game's Scatter, which can appear anywhere on the reels, is Thor's Hammer. You only need two scatter symbols on an active payline to trigger a win.

The scatter pays both ways: from left to right and from right to left. All the other symbols featured in the original Thunderstruck and the Thunderstruck II Slots pay only from left to right.

The Wildstorm Feature

The Wildstorm Feature will strike you as lighting. Because that's precisely what it is. When this particular feature is on, a wild storm forms on the screen and lightings will begin to hit the reels.

Wild Symbol winning combos with the WildStorm feature on Thunderstruck II

This is one storm to look forward to, as each time a bolt of lightning hits a row - it turns all the tiles on it into wilds.

The Wildstorm is a random feature, so you have no particular ways or combinations to trigger it. You can't predict the actions of Norse gods, after all.

The Great Hall of Spins

The bonus features included in the Thunderstruck II Slot don't stop at multipliers and wild storms. If you want to get some proper Walhalla action, you need to enter The Great Hall of Spins.

To enter the Great Hall of Spins, you need to land three or more scatter symbols on the reels.

This is where the magic happens and where you get to enjoy the best of Norse mythology.

Valkyrie's Spins

Valkyrie Bonus and Loki Bonus

In the first chamber of the Great Hall of Spins (first four times you trigger the feature), you meet Valkyrie.

She awards you with 10 free spins, each bearing a 5x multiplier.

You may re-trigger this feature four times. So, as you can imagine, the winnings can be heavenly.

But it's only the beginning.

Loki's Spins

When you trigger the feature for the fifth time and forward, you enter the Loki bonus.

Loki activates 15 free spins with a Wild Magic Feature.

It means you will land Wild Magic symbols which work as extra wilds. More substitutions = more winnings.

If you land two scatters during the feature, you'll get one more free spin. If three scatters - two more spins; if four scatters - three spins and if five - four free spins.

Odin's Spins

Odin Bonus and Thor Bonus

You'll meet the Odin Bonus only if you're lucky enough to activate the Great Hall of Spins for at least ten times.

On the 10th trigger, he shows up and gives you 20 free spins with an activate Wild Raven Feature.

Two of Odin's Ravens will be landing on the symbols and turning them into multipliers. One raven brings 2x multiplier, another one 3x.

If they both decide to stand on the reels, you get a whopping 6x multiplier for your wins.

Thor's Spins

You can activate Thor Bonus spins by entering the Great Hall of Spins for the 15th time and forward.

You get 25 free spins with Rolling Reels feature.

What are the Rolling Reels?

Every time you consequently win, the multiplier increases. This way, during most of your wins, you'll have a 2x or 3x multiplier, but it can go all the way up to 5x, too.

Bet Sizes

The Thunderstruck II slot features 243 fixed paylines with bets that start from a minimum of 0.30 per spin.

Those with the deepest pockets or who like to splurge when they play the free version of the Thunderstruck II demo online can go all the way up to 15 per spin.

Once you know whether you want to play Thunderstruck II for real money, for free, or with a bonus, open the game and select your bet size.

thunderstruck II play

First, select your coin size: from 0.01 to 0.05.

The winnings in the paytable are shown in coins. For example, five Thor symbols on a payline awards you win 500 coins.

Your coin size will determine what that will mean in the real money currencies.

If your coin size is 0.01 and you win 500 coins, you'll get 5. If your coin size is 0.05, you'll get 25.

Of course, that's if you bet 1 coin every spin. But you can also bet 2, 3, or more coins (up to 10) every spin. It multiplies the winnings accordingly.

One 0.01-value coin is equal to 0.30 of real money. Essentially, each time you increase the coin value or how many coins you bet per spin, you double your bet.

And you double your potential winnings.

When your bet size suits your bankroll, go ahead and press Spin. The Norse gods will flood your reels and decide the fate of your wager.
