Small Intro of Thunderstruck II

Microgaming is a software and game studio that sells online games to gambling sites and online casinos. It is privately held and specializes in gambling software with clients across the globe. Though it was established in 1994 and has 200 employees, it is a small and focused company with quality before quantity. Today, they also operate some popular subsidiaries such as Jackpot Factory Group. Just on July 9 of 2020, they released their first-ever title from Gold Coin Studios. Some of their most popular games are reprises of iconic movies and sitcoms. For example, Terminator 2, Halloween, Jurassic World is the flagship products. Besides them, proprietary themes like Jungle Jim Eldorado, Avalon II, Lost Vegas, and Thunderstruck II are 2020’s top-performing and most popular titles. 

As you can guess from the name itself, it takes inspiration from the mythology theme and is a modern slot, with a brilliant soundtrack, background score, rich 3D graphics, and awesome gameplay. It is more like a video game than a video slot. When you launch this game for the Free to Play the demo, it adds that epic melody to the air, playing through one of your open tabs on the browser. You can feel the aggression, the unfolding of a story.

If you played the Thunderstruck II slot before, you are going to love this sequel. With this sequel, players can win paytable achievements by completing all the win ranges, and for each symbol. When you unlock each symbol, your play table turns to gold. Besides these interesting features, the Thunderstruck II is a simple slot with 5 reels, a modest RTP, and a chance to win a whopping gigantic 2.4 Million Coins. 

Theme & Storyline

Thunderstruck 2 Slot Look & Feel

Thunderstruck II slot is a typical slot that depicts the God of Thunder, The Thor. Thus, is the name? In Norse mythology, this is a popular character and many gambling studios have at least a few slots in that genre. The theme is quite detailed with rich brilliant character design, artwork that has taken some serious amount of effort. Various Norse Gods, including Loki, Valkyrie, Odin, and Thor will meet you on the reels. As a player, the theme has been executed very well, and with a brilliant soundtrack and theme music, the video slot propels the theme forward with confidence. 

The storyline is also catchy in this sequel. In the Thunderstruck II slot, the players get a chance to play the Free Demo and take a look at the paytable. Here, the whole idea is to keep the players firmly fixed on the screen and the symbols. Therefore, there is no backstory or plot. You have to read the paytable to learn the features and how the storyline evolves.

All the symbols look flushed in the same theme artwork, except for the special symbols. You can play for the bumper prize and look for the Main logo, Thunderstruck II. This is the best symbol and the highest-paying symbol of the slot. In all, there are 8 special symbols, and as the story goes in the Nordic mythology, players have to break through castles, choose a weapon, and complete objectives to win a bonus. The bonus mark is the door to the Wilderness. 

Microgaming’s Thunderstruck Ii Slot’s Graphics, Sounds & Animation

There are a lot of slots with the same theme as this, out there; Most of the Norse mythology slots feature great graphics as well, but lack in gameplay winning. Here, we talk about the graphics and artwork in this slot too. Especially Microgaming’s dedication to composing a piece of special unique theme music that loops in short intervals. However, you can mute it as well. Beyond this, the animations in the Thunderstruck II slot are comparatively much better than its predecessor, which is a good addition. 

●      Graphics

The first thing one would notice is the consistency in theme and symbol art. The low-paying symbols such as the card letter J, K, etc. all look a part of the game itself. The frame, the background all feel consistent with the theme. Besides that, the graphics design for the symbols where Nordic Gods are depicted is of another level. There is a nice touch, finesse to it. You can immediately notice 2D style watercolor-style art. There is no 3D here, but the slot has a lot of 3D elements such as in the backdrop, the main character, and the logo. It is in symbols like Q, 10, etc. There is a lot of detail and attention to sketches such that they look realistic and not like a cartoon. This may be the biggest advantage of this slot in comparison with others in the same genre.

●      Soundtrack & Sound-Effects

No Norse slot is complete without great background theme music. IN this Thunderstruck II slot too, the team has put sincere effort into hiring a great composer. The music is a true piece of an icon for this slot. There are tons of slots out there, and this slot makes a great impression from its music alone. Besides the theme music, there is a standard set of sound effects such as reel spins, triggering with events like bonus games, big wins, and so on. However, after a short while, the theme music might seem a little bland, but for the first 30 mins or so, it really adds to the aggression and vigor of playing a myth-genre epic battle video game. 

●      Animations

Now, this is the part that makes Thunderstruck II stand out of the crowd too. Without much fancy, the animations show up and play well. They are not there just for the sake but have a lot of details in them. These get activated during bonus games, big wins, and are event-only triggering. You would not feel anything less when playing this slot here. They load quickly and play well even on a browser with full-screen settings. For example, when you win something, the Thunderstruck II Logo opens up from the middle like a door and releases your wings. The sound uplifts and becomes intense. It is so ecstatic if you sit in front of your laptop and play this. 

Thunderstruck II Special Bonus Features, Free Spins, Progressive Jackpots Etc

Thunderstruck II has loads of features to make this game as appealing as possible. As the slot comes with barely the average RTP, there is a need for bonuses and Free Spins. Fortunately, this video slot has a BONUS symbol, Thor’s Hammer. Players can expect to win some serious real money during these feature rounds, and to get into them, have to bet considerably higher. Besides the regular Wilds, there is a special feature called Wild Storm, and the Great Hall of Spins. The latter comes with 4 options to pick from and we shall discuss them in detail below. 

1.    Wildstorm

Thunderstruck II is a much more advantageous game than the other Norse theme video slots. In this game, the Thunderstruck II Logo symbol is the Wild. This means that it substitutes all other symbols on the reels, except for Thor’s Hammer, the Bonus Mjölnir. Furthermore, the logo has other benefits. Whenever a player hits a winning combination during the spins, The logo is available on the reels, which will double the winning rewards. But, when the Wild Storm feature activates, some things change. During the Wildstorm feature, this logo symbol ceases and is no more a Wild symbol. 

Players must know that this Wildstorm Feature gets randomly triggered and does not give a hint so that players can bump up their bets. When active, it will turn as many symbols as possible to WildS on the reels. But, you cannot trigger Free Spins during this feature, which is a letdown. When this feature randomly strikes, like a clap of thunder or lightning, it can turn up to 5 reels full of Wilds. This means that you can wait to reap a lot of benefits from a single spin. 

2.    Great Hall of Spins & Bonus Games

The best and main feature of this video slot is this. The sequel brought back a lot of things that people liked and introduced some more. In the Thunderstruck II slot, players can move through the storyline and unlock Multi-Level Free Spins, and bonus features. They need to get 3 or More of Thor’s Hammer BONUS symbols for that, and this will trigger this feature. As the icon stands for, there are several bonus games in this round. With multiple entries, the Great Hall of Spins will sequentially pave the way for more wins and bigger rewards. 

  • Valkyrie Bonus;
  • Loki Bonus;
  • Odin Bonus;
  • Thor’s Bonus;

Above are the 4 major bonus games or rounds in the Thunderstruck II slot. Microgaming’s team did a wonderful job with these. 

●      Valkyrie Bonus

It is a simple feature. If you triggered the Hall of Free Spins between the 1st and 4th bonus, might trigger this game. In this game, players will win 10 Free Spins. Furthermore, all the wins will receive a multiplier of 5x. If that was not enough, you can retrigger more Free Spins inside the Free Spins. 

●      Loki Bonus

It is triggered between the 5th and 9th bonus feature triggers. When this part of the story unfolds, players will win 15 Free Spins. This comes with its own Magic Wild Feature. Where a Magic Symbol will appear and it will randomly transform the symbols on the reels to additional Wilds. Now, 2, 3, 4, or 5 of Thor’s Hammer will fill up your screen and this will trigger 1, 2, 3, or 4 additional Free Spins. Though less attractive than Valkyrie, it still has a great punch if you are lucky.

●      Odin Bonus

It is a feature that triggers when players reach the third phase of the game. When you trigger this feature between the 10th and 14th trigger of the bonus feature, players will win a major 20 Free Spins. This comes with a Wild Raven Feature. When Odin’s Raven will fly across the screen with wonderful magical animation, the symbols on the reels will randomly turn into 2x and 3x multipliers. Then, players will receive up to a 6x multiplier if both Odin’s Raven appears on the reels together. 

●      Thor’s Bonus

It is the most attractive and best pay bonus game of Thunderstruck II. This will trigger during the 15th and above bonus triggers. It is the last and most rewarding, therefore. Here, your Free Spins become a staggering 25 and come with an added bonus of Rolling Reels. In this, the consecutive wins will increase your current multiplied by 5x. Thus, the Rolling Reels have the potential to award the players multiple times during the spins. 

Progressive Jackpot

Despite such large pays and huge potential to win up to 2.5 Million coins, players may not be satisfied. But, to focus on the main game, Microgaming does not accept Thunderstruck II in a jackpot network, even though they themselves own one. The jackpot or highest pay amount in this video slot through the regular game is 6000x the bet amount, in a single spin. 

What are the Thunderstruck 2 RTP & Variance?

The RTP of any slot is an important deciding factor. With the Thunderstruck II slot, this is an average figure of 96.65%. But, from one casino to another, the figure may vary. RTP is always an estimate determined mathematically. It tells if a player will bet how much they can get in return. For example, in Microgaming’s Thunderstruck II, if a player plays for a very high number of spins, for every $100 spent, he can expect only $96.65 in return. 

The Thunderstruck 2 Variance is High. This means the player hit few winning combinations. But if a player hits a combination payouts will be great.

What does the Thunderstruck 2 Paytable look like?

Thunderstruck II has a single-page information booklet. It has all the high and low-paying symbols. Thunderstruck 2 has a list of symbols you should look out for and more. It is readily accessible from the top-left side of the screen with ‘Three Horizontal Stripes’.

The Thunderstruck II Logo symbol is the highest-paying icon. With 5 of them on the reels, players can win a record-breaking 1000x their bet. But, it falls down to just 75x if 3 appear on the reels. The next high-paying symbol is Thor. The Bonus symbol pays 200x for 5 while the smallest of the set pays 250x for the same number of symbols. It is the Boat. The rest Low-Paying symbols are the card letters like A, K, 9, etc. and they pay very low. Almost, close to nothing. For example, if you find reels full of as that is, 15 because this is a 5×3 reel, you will win 450x the bet.  

How to Win/ Strategy for the Thunderstruck II Online Slot?

Any strategies for the Thunderstruck II slot may not be that fruitful. This is because the slot is a high volatility slot. Even the variance is HIGH. The only best part of this slot is that the bonus rounds are plentiful with rewards and surprises. If you are a high-roller gambler, then this slot is best for you. So, a recommended rule of thumb is to keep your bets as high as affordable per payline, for as long as possible. 

Final Verdict

Thunderstruck II from Microgaming is a true sequel and modern-day slot. It has the richness of today’s 3D graphics, artwork that is crisp and flourishes with beautiful tones and shades. The RTP is average and there are plenty of bonus games. With so many Free Spins, that even re-trigger, players have a wonderful opportunity to win big.
