Thunderstruck Slot - Review, Demo Play, Payout, Free Spins & Bonuses

Introduction to Thunderstruck

Thunderstruck is one of Microgaming’s most popular online slots games. It started a number of trends in the online gambling world, and it has even inspired the creation of Thunderstruck II, which builds on the success of this title. Another reason Thunderstruck is so popular is due to its theme. Featuring Norse gods, Thunderstruck presented something completely new to the online gambling world. Never before had an online slots developer focused so much attention on creating an immersive world for players. It presented a brand new gaming experience, and players certainly appreciated it. However, the game has become quite outdated.

The game only offers one bonus round, which is very simple. When the bonus round is triggered, it is up to the player to predict the colour of the next card. If they do so successfully, then they earn a bonus prize. In the years since Microgaming released Thunderstuck, it has become commonplace for games to include free spins and more creative bonus rounds.

Thunderstruck RTP (payout) & volatility

The RTP - also known as the return to player or the payout ratio - for Thunderstruck is 96.1 per cent. This number is calculated by a computer and refers to how much is paid out for every 100 spent in the game. This makes it easier for players to work out how risky a game is, but it is important to be aware that this number is theoretical and is based on a long period of time - the more games you play, the more likely you are to average a return of around 96.1 per cent. You should never solely use the RTP to decide whether you will spend money on a slot; after all, you can never predict how the reels will fall or when a big win is just around the corner!

Thunderstruck also has medium-high volatility. This means that the game has a few big wins, but the big wins are not frequent - you might have to play for quite a while to encounter one! The game also has a few smaller wins that are more frequent. Over time, you can build up some decent cash prizes; however, it is important to state that medium-high volatility slots are riskier than low volatility slots, as there are fewer wins. If you have a tight budget, you may prefer to find a low volatility slot with more frequent prizes.

Thunderstruck slot graphics & theme

Thunderstruck has a Nordic god theme. This theme is quite popular with slots, but it seems that this particular slot is one of the most popular Nordic slots. This could be due to the generous bonus features rather than the theme; however, you should definitely check Thunderstruck out if you like to play Nordic slots.

The graphics are admittedly pretty basic for this game. When the slot is loading, you will see the game logo in a dark red font. Behind this, you can see the Nordic god Thor, who does not look particularly godly; in fact, he looks like a fairly standard man with a helmet, but at least he has an impressive flowing blond beard.

Once the game has loaded, the reels will appear on the screen. The reels comprise blue, stone-like boxes, with the symbols appearing on top of each box. At the bottom of the screen is a control panel, while information about the game can be found at each side of the reels.

The symbols also fit in with the stone theme. All of them are cracked - which makes sense if they are all constantly falling on top of each other - and some fit in with the Nordic theme, such as Thor’s hammer. The game also has some low paying symbols that are represented by playing card numbers. These symbols are also made from cracked stone, which is another nice touch.

Overall, the graphics in Thunderstruck are simple and colourful. They have a familiar style that may remind you of children’s books, but we like the final effect. The simple format makes it easy to focus on the game, while the pleasant colours are very appealing.

How to play Thunderstruck slots

If you have played online slots before, you should have no problem getting started with Thunderstruck. This is because the game has a common reel format - a five by three grid - that is found in many other slots. The one thing that you do need to do before you start playing is to set your bet level, which you can do using the control panel at the bottom of the reels.

The game has very low bet limits, which is perfect for players who do not have lots of money to spend; however, the range does not go very high. The lowest possible bet per spin is 0.09 and the highest bet you can play is 0.45. This is not ideal for big spenders who want to take a huge risk, as it means you can’t place massive bets; however, the game does have some pretty big cash prizes and even placing a small bet can see you win big!

Once you have set your bet level, you can start to spin the reels. If you want to do this manually, simply click the spin button; if you want the reels to keep spinning, you can use the autospin feature. This will spin the reels automatically for a set number of spins, such as five spins or 20 spins, so you do not have to press the button every time. This makes the gaming experience more efficient but also less engaging. If you can only play for a short amount of time, we suggest that you spin the reels yourself.

How to win at Thunderstruck slot

If you want to form a win in Thunderstruck, you will need to get at least three matching symbols in a row. This will result in an automatic payout; however, it is important to be aware that the bigger the combination, the bigger the cash prize. If you get four matching symbols, you will win a bigger prize; if you get five matching symbols, you will win even more cash. Keep an eye out for the big symbol combinations!

It is also important to be aware that different symbols have different values. The low paying symbols for the game are represented by playing cards, while the high paying symbols are represented by Thor’s hammer, a horn, a castle, and other Nordic-themed items.

There are also two special symbols to look out for. Thor himself represented the wild symbol for the game, which can be used to replace any standard symbols on the reels; obviously, this makes it easier for you to form wins throughout the game. There is also a scatter symbol, which is represented by a ram. This can be used to activate the game’s free spin bonus round.

Thunderstruck tips, tricks, cheats and strategy

We do not have any cheats or tricks for Thunderstruck, as the outcome of every spin is random - as with all other online slots. This makes it impossible for anyone to predict how a game will go, so cheating is impossible - but the randomness is part of the fun!

We do have a few tips and strategy suggestions to ensure you have an enjoyable and safe gaming experience. Before you start playing, we suggest that you set a time limit, as this means you are less likely to overspend. It can also be useful to set a budget, especially if you have limited funds available.

If you are worried about your gambling habit, we recommend that you talk to someone. There are lots of businesses and websites that can help; for instance, if you live in the UK and are concerned about your gambling, you can ring the Gambling Commission for help and advice. Don’t be nervous about calling - the service team has lots of experience with gambling addiction and will do everything it can to help you.

Thunderstruck demo play / free play

It is possible to play Thunderstruck for free in addition to playing for money. Playing for free does not appeal to everyone - after all, you can’t win real money this way - but there are lots of benefits to playing for free. It will teach you more about how often the special symbols and bonus features appear, and you will have a more realistic idea of the payouts you can expect. This is very useful, especially for players who do not have much to spend. If you decide to play for free first, we suggest that you use the same bet level you would use if you were playing for money. This is because payouts are affected by your bet level: the more you bet, the more you can win. If you place a huge bet in free play, the wins will be huge, but they probably will not be as big if you set a smaller bet when you play for money.

Thunderstruck slot on mobile - Android, iPhones and tablets

Thunderstruck is not only available on computers and laptops; in addition, you can spin the reels using your mobile or tablet. The game has been optimised for all devices, which means that it will resize to fit any screen. If you prefer mobile gaming, this is definitely not a problem.

Thunderstruck review & rating

Thunderstruck is one of the most popular online slots; if you play the game, you will soon see why. The graphics may be pretty basic, but the gameplay more than makes up for this. The medium-high variance means there are plenty of big wins hidden in the game, while the fast-paced action makes every reel spin exciting.

The game also has a selection of generous bonus features for players to discover, including a free spins bonus round and a gamble feature that can double your winnings. If you like free spins, you will probably love this slot; however, if you hate basic graphics, you might want to pass on this one.
