Thunderstruck II Streams 2020 [Sep-Oct]

So, my name is Rhyker. I am developing my own blog about real money casinos. Today I want to share my studies on one of the very best online slot machines which hit casinos in far 2010, Thunderstruck 2.

It is the sequel to Thunderstruck (The original game first emerged on the market in 2004), however, which is not nearly as good as Thunderstruck 2. In a Thunderstruck vs Thunderstruck II Battle happened during my streams, the sequel was a clear winner. But that’s not what I’m talking about today.

In the review, I’m going to begin with the results of my real money play solely at Thunderstruck 2. You can check any paragraph of interest, but it’s better to start with my real money streams video overview above. Then you will understand what exactly might happen during your gameplay and how much money this slot pays in practice. Otherwise, the key findings and my verdict are at the end of the Thunderstruck 2 slot review.

Thunderstruck 2: Getting Started for Real Money

It’s one hundred percent safe to play for real money at online casinos I recommend. The video slot RTP is attested by eCOGRA and casinos are licensed by the authorities like Malta or/and the UKGC, and more importantly, it carried out my experimental check!

All that’s left to do is to register with a real-money Microgaming casino, make a deposit of $10 or $20 for a start, and launch Thunderstruck 2 to reap some benefits! What exactly are the benefits? That part is coming next.

Bet Limits & Jackpot Levels

Thunderstruck 2 Paytable

As there’s not payline but rather 243 ways to win. I played with a minimum stake, which is 30 cents, you can’t go with less wager here. And I haven’t raised bets though it is possible to bet $15 per spin. In the case, my wins would be of about $1,633, I guess. But you never really know what can happen.

Quite apart from the fact that it’s an old game, there is Auto Play function, very basic though. See, I’ve chosen to play 100 auto spins, but you can set up 10, 25 or 50 ones. If you ask me, here I’ve won different awards rather often. However, I haven’t been fortunate enough to get out the maximum8,100x a bet/$121,500 – during free spins rounds in the Loki feature on conditions that the Wildstorm is in play too.

Thunderstruck 2 Slot Symbols

In any of the paying lines, a combination of 3 to 5 of any symbols in a row results in a small or rather big win. Let’s check the highest-paying icons themed on the Nordic mythology and lower-paying cards typical for casinos.

  • High-paying icons: Viking Ship, Valhalla, Thor’s Hammer, Odin, Loki, Thor, Valkyrie, Thunderstruck II logo.
  • Low-paying icons: card suits from 9 to A.
  • Wild – Thunderstruck 2 Logo takes place of all symbols but the Scatters and doubles every win.
  • Scatter – Mjölnir symbol, better known as Thor’s Hammer, is capable of opening bonus rounds. It also plays a special role in Loki round, bringing up to 4 extra spins.

4 Free Spins Features Review

Thunderstruck 2 Bonus Features

How to enter bonus games? Oftentimes, people think they can win 25 Free Spins or up to 6X Multiplier right when they start the gameplay. They’re wrong. Bonus features can be played this and no other way. Now let me explain to you that in detail.

How to Get into the Great Hall of Spins

Collect 3, 4 or even 5 scatter icons, the Hammers, and you are in! Now let me relate the things as they actually happen below.

Level 1: Valkyrie Feature

If 3-plus Bonus Hammers appear, Valkyrie Bonus is activated. Here you get 10 Free Spins, where each win is multiplied by 5 times. And I enjoyed it all the way. I’ve been playing it 4 times before I could proceed to the next level.

Level 2: Loki Feature

3-plus Bonus Hammers caught on the 5th time unlocked the Loki Bonus for me. Here are up to 19 Bonus Spins on offer. 15 Free Spins + additional 1-4 if you trigger 2-5 scatter symbols respectively. Plus, if Wild Magic logo appears on the 3rd reel, it begins to act like the wild – replaces other icons. Potentially, it can be very rewarding.

Level 3: Odin Feature

Having got 3 scatters for the 10th time, I leveled up to Odin, where 20 Free Spins and 2X, 3X Random Multipliers are available. To win the highly-anticipated 6X Multiplier, 2 Ravens should go down on the reels at a time. In my experience, it happened to me, maybe, once or twice only. More ofte, I got 1 Ravens that turn symbols into 2x only.

Level 4: Thor Feature

And I’m still looking forward to unlocking Thor to FINALLY get the maximum amount of Free Spins – 25. It has Rolling Reels feature, which gives the potential to win more at the same spin. It looks like this. You make a win combo of 3 Viking Ships. You get paid, then these 3 Viking Ships disappear. Other symbols fall on their position. The process repeats itself until you stop winning.

Here, with each respective win, the prize is set to be multiplied by 2X, 3X, 4X or 5X. And all that can happen to you at one spin! Or it won’t happen. The multiplier resets to 1x when the “cascading” icons don’t form a prize combination. Unfortunately, Thor’s Free Spins cannot be re­activated.

Thunderstruck 2 [Random] Wildstorm

Thunderstruck 2 Wildstorm

Wilds come by storm, completely randomly. It’s all about the next speciality of the casino game. I haven’t seen too wild wins during the wild storm, however, potentially, 5 reels turning up wild can result into a big catch – a win of 3,000x the stake.

Personally, I’ve got only 2 reels covered with wilds once. But you have to differ reels from paylines. Only 5 wilds on a payline are worth 1000x your bet, which means having two entire reels of wilds pays according to the paytable of other symbols surrounding them.

Slot Design: Realm of Asgard Overview

The Norse mythology-themed game is made around the Norse God of Thunder. With a cool soundtrack playing as I spun the reels, I’ve joined Thor on his adventure with 3 more ancient Norse gods. And all it happened in the realm of Asgard. However, the graphics is a bit outdated. No wonder it was launched 10 years ago already.

What Rhyker Thinks: My Verdict on Thunderstruck 2

Rhyker Hackary is satisfied with Thunderstruck 2 improvements, most notably, 4-level free spins bonus games reflecting 4 Supreme Beings, aka the Hall of Spins feature. In fact, I can even say I’ve progressed in this fun slot game pretty fast during my gameplays. Check the sneak peek video of my streams. At this point, I’ve unlocked 3 out of 4 features, more specifically, Valkyrie, Loki and Odin. Overall, the wins were bigger than my losses.


  • What’s Thunderstruck 2 slot RTP?
  • Averagely, it’s supposed to pay back 96.65% of money but in a long-long run. In my case, after every 100 spins made, my balance jumped from -$17.84 to +$72.35 as seen on the graph that you’ll find in my Thunderstruck 2 review of the slot. Overall, I even made $30 on it. So, I can recommend it as a truly paying machine.
  • Can it be that Thunderstruck 2 is rigged?
  • As to eCOGRA testing reports, Microgaming slots always have the same return no matter what casino you play Thunderstruck 2 in. This’s so because the company actually sets the RTP on the development stage of each machine and casino owners simply don’t have such access. But you should realize that 96.65% of money has been paid out to all Thunderstruck 2 players within a casino but how much cash a particular gambler can win at a time can’t be calculated.
  • Can I go mobile with Thunderstruck 2 slot?
  • Sure, I tested the game on my iPhone. However, I know you can do the same using an Android phone since Microgaming revamped Thunderstruck 2 using HTML5 technology long ago.
