Thunderstruck II

Have you ever imagined standing in the great halls of Asgard while Thor sends bolts of lightning crashing down all around you? Do you love the old Norse legends of Odin, Loki and the Valkyries? Well then, Thunderstruck II is one slot you must try at least once. It was first released by Microgaming way back in 2010 as the sequel to the original Thunderstruck, and it now sits in the Games Global portfolio. To be honest with you, the sequel went on to become a lot more famous than the first game ever did, and even today, more than fifteen years later, it is one of the most recognised slot names you will come across on UK casino sites, including ours here at Spinzwin.

The game has a slightly different setup from the usual online slot. You get a grid comprising 5 reels and 3 rows, but there are no fixed pay lines here, instead the game offers 243 ways to win, so matching symbols only have to land on neighbouring reels from the left, whichever row they show up on. The RTP is 96.65% and the volatility sits somewhere between medium and high, hence the smaller wins may possibly come along at a fair pace while the bigger ones are mostly saved for the bonus rounds. The maximum win holds the potential to reach a whopping 8,000x your stake.

What makes the game so special is the Great Hall of Spins, a free spins feature with four levels that you unlock one at a time, each one ruled by a different god. Along with it, there is a random Wildstorm feature in the base game and a wild symbol that doubles your wins. What are you waiting for? Launch Thunderstruck II at Spinzwin and see if Thor is in a generous mood today. This article describes in detail the special features, symbols, and instructions of the game. Go through it to have a better understanding of the game:

How To Play Thunderstruck II

Thunderstruck II runs on the Games Global interface, which is simple and neat, making it easy to follow for players of all levels, from seasoned pros to someone spinning a slot for the very first time in their life. Once the game loads, you will see the reels placed in the middle of the screen inside a frame of old grey stone, with the Thunderstruck II logo at the top, and all the buttons you need are lined up along the bottom of the screen. The layout may shift a little between the desktop and the mobile version, but the buttons themselves stay the same.

On one side of the bottom bar you will usually find the menu icon. Clicking on it opens up the paytable, the game rules and the settings, and we really recommend giving the paytable a quick look before you start, because it shows you the exact value of every symbol at the stake you have picked. Near it is the sound button, in case you want to switch off the thunder while playing somewhere quiet. Since you are playing from the UK, you may also notice a clock and a session timer on the screen, so you always know how long you have been at it.

Next comes the bet setting. As there are no pay lines to pick in this game, the only thing you need to choose is your total stake per spin. The minimum bet starts from 30p per spin, and the maximum is capped at £5 per spin as per the UK stake limits for online slots, or £2 per spin in case you are aged between 18 and 24. Do you like playing big? Is the top stake the only one you ever pick? Well then, you may go right up to the cap, but the higher the bet, the quicker your balance moves, so set it with a bit of thought.

Once your stake is set, hit the large round spin button, usually found on the right side of the controls, and the reels will start rolling. You will not find an autoplay option in this version of the game, as autoplay is not allowed on online slots in the UK anymore, hence each spin is one you press yourself. Some players miss it at first. Honestly though, it makes it much easier to keep track of what you are spending. Your balance, the bet for the current spin and the amount won on the last spin are all shown in the thin band running along the bottom of the screen.

Make sure you have a fixed budget in mind before you start and stick to it. Real gambling comes with real risk, and hence, you must play responsibly. At Spinzwin, we take the matter of responsible gambling very seriously and have a whole page dedicated to it, with links to support services such as GamStop and BeGambleAware for anyone who needs a hand.

That’s it! Isn’t that simple?

Theme, Design, and Audio

Thunderstruck II takes you deep into Norse mythology, right up to Asgard, the realm of the gods. The reels are set against a cold, stormy backdrop of blues and greys, the frame looks like it has been carved out of old stone, and every now and then lightning flickers across the screen, adding a sense of drama to even the quietest of spins. For a game that came out in 2010, it has aged really well. The colours are darker and moodier than the bright, shiny slots you see today, but that suits the theme perfectly, it is a storm after all.

The symbols are well-rendered and full of detail. You get the four main characters of the story, Thor, Odin, Loki and Valkyrie, each one drawn with their own look and personality, along with Valhalla, the great hall of the gods, and a Viking longship. The Thor’s Hammer is the symbol that opens the bonus, while the Thunderstruck II logo acts as the wild. The low-paying ones are the card symbols from 9 to A. Understandably, considering the year of release, the animations are not as flashy as in the newer games, but a good win still lights up the reels nicely.

Coming to the audio, it really deserves a special mention. A slow, booming orchestral score plays in the background with the odd rumble of thunder thrown in, and it truly builds up the tension as the reels slow down one after another. Each of the four levels in the Great Hall of Spins also comes with its own music and its own colour scheme, so every time you unlock a new god, the game feels fresh all over again.

Gameplay

The gist of the game is the same as most online slot games – one must land winning combinations of identical symbols to possibly earn prizes. However, as mentioned earlier, Thunderstruck II does not use pay lines. It runs on 243 ways to win, so a winning combination is formed whenever 3 or more matching symbols land on adjacent reels starting from the leftmost reel, in any position on those reels. In case the same symbol appears twice on one reel, that counts as two separate ways and both of them are paid, increasing the chances of the players landing more winning combinations.

Now here is the thing about Thunderstruck II, the base game can be fairly quiet at times, and that is normal for a slot with medium to high volatility. A few spins may go by with small wins or nothing at all, and then the Wildstorm crashes in out of nowhere, or three hammers land and off you go to the Great Hall. So don’t get put off by a slow patch. Set your budget, keep your stake at a level you are comfortable with, and remember that every spin is random, no matter what happened on the one before it.

Special Features

Thunderstruck II has a few special features that add fun twists to the simple gameplay, offering you chances to possibly land much larger wins. Brief descriptions of these special features are given below:

Wild Symbol

The Thunderstruck II logo is the wild symbol of the game. It substitutes for all the regular symbols except the Thor’s Hammer bonus symbol, helping you complete the combinations that were one symbol short, increasing the chances of the players landing more winning combinations. On top of that, any win the wild is a part of gets doubled, which is a really handy extra in the base game. The wild also pays on its own, and landing 5 of them holds the potential to award 33.33x your stake, the highest regular symbol payout in the game.

Wildstorm Feature

Wildstorm is a random feature that may strike on any spin in the base game. When it does, Thor’s lightning comes crashing down onto the grid and turns anywhere from 1 to all 5 reels completely wild. Imagine the whole screen covered in wilds! In case all 5 reels turn wild, you may possibly win the top prize of 8,000x your stake, which works out to around £40,000 at the £5 maximum bet. It does not happen often, mind you, but when the thunder starts rumbling, it is definitely one of the most exciting moments the game has to offer.

The Great Hall of Spins

This is the feature that made Thunderstruck II so famous. To enter the Great Hall of Spins, you must land 3 or more Thor’s Hammer symbols anywhere on the reels. Now here is the twist, you do not get all the free spins modes from the very start. There are four levels in the Great Hall, each one based on a different god, and they unlock one by one as you keep triggering the feature. Once a level is unlocked, you get to pick it every time you enter the Great Hall after that, so you are not forced to play the same one again and again. As per the game rules, your progress is saved as well, so you don’t lose your unlocked levels when you close the game and come back another day.

Valkyrie

Valkyrie is the level you get from the very first trigger, and she is the only one available for your first four visits to the Great Hall. She awards 10 free spins, and every single win during these spins is multiplied by 5x. Landing 3 or more hammers again during the feature will retrigger it for more spins.

Loki

Loki unlocks on your 5th trigger. He offers 15 free spins, and during these spins his Wild Magic symbol may appear on the reels and turn random symbols into wilds, increasing the chances of the players landing more winning combinations. Loki’s free spins can also be retriggered for a few extra goes.

Odin

Keep going, and on the 10th trigger the doors open for Odin, who hands you 20 free spins. During the feature, his two ravens may randomly land on the reels. One raven adds a 2x multiplier and the other one adds a 3x multiplier, and in case both of them are part of the same win, the multiplier becomes 6x. Do note that Odin’s free spins cannot be retriggered.

Thor

Thor is the final level, and you have to keep triggering the Great Hall until the 15th time to unlock him. He brings 25 free spins with the Rolling Reels feature. Every time you land a win, the winning symbols disappear, new ones drop down to take their place, and another win may possibly follow. With each win in a row, the multiplier climbs higher, going up to 5x. It takes patience to reach this level, no two ways about it, but the wait may truly feel worth it once you finally get there.

Symbols

The symbols can be categorised into two based on their worth: high-paying and low-paying. The high-paying ones include symbols, such as Thor, Odin, Loki, Valkyrie, Valhalla and the Viking longship. These symbols are unique and adhere to the game’s theme. The low-paying ones are the classic card symbols, such as 9, 10, J, Q, K, and A.

Thor is the highest paying of the regular symbols. The winning amount depends on the number of symbols that form the winning combination. The higher the number, the larger the prize. For example, a winning combination comprising 5 Thor symbols will offer an award of 16.67x the stake size. While a winning combination comprising 4 Thor symbols will offer a lesser award of 3.33x the stake size only. The Viking longship is the lowest of the high-paying group, with 5 of them paying 8.33x the stake size.

Look out for the special symbols, such as the wild and the Thor’s Hammer, they have the power to trigger further bonuses.

Pay Table

As mentioned above, Thunderstruck II is played on 5 reels and 3 rows with 243 ways to win, and the symbols are split into the high-paying gods and the low-paying card symbols. The values below are shown as multiples of your total stake. Do check the in-game paytable for the exact figures at your chosen bet.

RTP and Volatility

Thunderstruck II offers an RTP of 96.65%, which is slightly higher than the industry standard of 96%. If you don’t know what RTP is, it is the amount of wager a player may receive as a return from the game over a very long period. This means that for every £100 wagered, the game offers a return of £96.65 in theory. It is essential to note that this is a theoretical value obtained after assessing millions of spins, hence, the return is not guaranteed and your own session may turn out very differently.

The volatility of the game is medium to high. This means the wins may not land as often as they do in a low volatility slot, but they hold the potential to be bigger when they do come, especially once you start unlocking the later levels of the Great Hall. You may have to strengthen your patience a little and be ready for a few dry spells along the way. Never chase a loss.

Thunderstruck II is Available on Mobile

Are you tired of being stuck at your desk every time you want to play? Don’t worry; Thunderstruck II is fully optimised to be playable on both iOS and Android smartphones and tablets. The game first came out at a time when most people still played slots on a PC, but it has been brought up to date since then, and the mobile version is identical to the desktop one, with the same reels, the same Wildstorm and the same four levels in the Great Hall. You can now enjoy your game while commuting to work or while waiting for the kettle to boil. All you have to do is open the Spinzwin website on your mobile browser, log in, launch the game, and enjoy it anytime, anywhere.
