First Impressions of Thunderstruck 2
We’re huge fans of Norse mythology, so that’s a definite bonus for us. More can be said for the graphics though. Even though the game was first published in 2010, it still feels a lot older than that. Perhaps that’s due to the ‘graininess’ of the artwork. Despite this, the scatter and wild symbols are easy on the eye. The music, on the other hand, is incredibly captivating. Very peaceful and melodic. Games like this remind us why Microgaming is still one of best casino software suppliers in the world.
How to Play Thunderstruck II Slot
The first thing you should notice when the game loads is a message promoting a new feature for Thunderstruck. It seems that Microgaming is introducing achievements. This means that you need to open the bonus game multiple times in order to progress. Let’s not get overwhelmed by this yet. Here’s a quick overview of the features before we discuss them in further:
|Slot Name||Thunderstruck 2|
|Free Spins||Yes (10-25)|
|Bet Range||£0.30 – £15|
|Return to Player (RTP)||96.65%|
Majority of the most popular casino games are very easy to get started with. Thunderstruck 2 is no exception to this. Here are three simple steps to get you started:
- Adjust the coin size using the + / – buttons, located below the dial, at the bottom of the game. The minimum is 0.01 and the maximum is 0.05.
- Next, select the number of coins you’d like to play with for each spin. The minimum is 1 and the maximum is 10.
- Check the amount of your bet under the ‘bet’ section before clicking ‘spin’ to get going!
There are some advanced features to check out if you feel confident. It’s quite subtle, but you should see an ‘expert’ button in the footer bar. Clicking this will change the layout of the betting area somewhat. Note: this might change depending on the version you’re playing.
The coins area splits to provide an autoplay feature. Here you can fine tune the autoplay settings for:
- The number of spins to play
- When to stop spinning, based on a decrease in your balance, or if a win exceeds or equals a certain amount
Autoplay is generally used for people who want to walk away from their PC or mobile device; particularly useful if you need to wager through a casino bonus.
Thunderstruck II Slot Symbols
Here’s the breakdown of the different symbols and the min/max coins of potential winnings. Please note that Thunderstruck 2 pays left to right for adjacent symbols only. Some slots will pay right to left too, and for non-adjacent symbols.
Symbols and Wilds of Thunderstruck II Slot
There are some seriously engaging and fun features to this online slot, namely:
- Wildstorm feature
- The Great Hall of Spins (the slot is worth playing for this alone)
Thunderstruck II – Wild Symbols
The wild symbol is the game’s Thunderstruck II logo; a blend of lightning blue storm chaos. This substitutes for all the symbols in the above table apart from the scatter symbol, which is Thor’s Hammer with ‘BONUS’ emblazoned on the side. If the wild symbol appears across any winning payline, the winnings are doubled.
Thunderstruck 2 – Scatters
The scatter symbol is Thor’s Hammer and is what triggers the awesome Great Hall of Spins, where other bonus features can be unlocked; more on this coming up!
Thunderstruck II – Wildstorm Feature
The Wildstorm feature has a random chance (of which the percentage is unknown) of occurring. If it does occur, any of the reels can turn wild, greatly enhancing your winnings. Note that free spins can’t be triggered during the Wildstorm feature.
The Great Hall of Spins – Thunderstruck 2 Slot
Here we go, the ultimate feature of Thunderstruck 2! This where you’ll unlock free spins, multipliers and the chance to win BIG!
This bonus game triggers from Thor’s scatter symbol. You’re looking for at least 3 of these anywhere across the reels to get started. Successive spins in the normal game revealing the scatter symbol will progressively unlock some of the best casino slot bonuses that Thunderstruck II has to offer.
The games are centered around these famous Valhalla individuals:
When entering The Great Hall of Spins, you’ll see these four characters lined up. You’ll have to select the game you want to play, but they won’t all be available from the start. It is in your best interest to play the furthest game to the right; you’ll see why shortly when you read about the features of each game. All spins are automatic, so just sit back and watch the reels turn over and your winnings go up… hopefully! All winnings are multiplied by the bet amount immediately before playing the bonus game.
Valkyrie Bonus Game – Thunderstruck II
Valkyrie will be your host for the bonus game from the 1st to the 4th time of playing The Great Hall of Spins. The graphics have now changed slightly to be more aligned to Valkyrie’s artwork. The symbols remain the same as per our symbol table.
You’ll immediately be awarded with 10 free spins when the game fires up. All wins for each spin will have a 5x multiplier attached to it and free spins can be earned during the game. When the free spins are over, you return back to the normal game with your new winnings in your bank.
Loki Bonus Game – Thunderstruck II
After revealing Valkyrie’s bonus at least 4 times, Loki will show up from the 5th time all the way through to the 9th. Now the game has turned into a sneaky green style, with Loki’s prying eyes sitting above the reel. 15 free spins are on offer here, so a slight improvement on Valkyrie’s 10.
There’s also an added ‘Wild Magic’ feature with Loki, specifically on the 3rd reel. If it does appear here, there is a random chance for it to convert other symbols into additional wild magic substitutes. These basically act as wild symbols, with the original Thunderstruck II logo still remaining as a wild.
Further free spins can be won here by revealing the scatter symbol. You need at least 2 across any of the paylines, which will award 1 free spin. 3, 4 or 5 scatters will award 2, 3 or 4 free spins respectively. When you have no free spins left, you’ll return to the regular game with your winnings.
Odin Bonus Game – Thunderstruck II
If you manage to get through Valkyrie and Loki, Odin will be available from the 10th time the bonus feature is revealed. Now we’re looking at the starry sky above Valhalla with a dark raven theme.
This time, you’re awarded 20 free spins for your efforts and the wild symbol changes from Loki’s Wild Magic to Odin’s Ravens. If during the free spins you get a winning payline, one of the Ravens will fly down and convert a symbol to a multiplier. These can be either 2x or 3x, and that winning line on the free spin will pay out at the revealed multiplier.
There is a smaller chance that both ravens will fly down. If this does happen, there is a chance that a payout of 6x can occur! If you have no more free spins remaining, your winnings are added to your bank and you’ll return to the normal game.
Thor’s Bonus Game – Thunderstruck II
If you manage to get this far, congratulations! You have now unlocked the God of Thunder’s game. Thor will now be an option for you to select out of the 4 characters from the 15th trigger of the bonus feature in normal play.
The game is now in an electric blue theme with rock music blasting in the background. You’re now granted a whopping 25 free spins and the wilds feature has been replaced with Rolling Reels, which are linked to multipliers. How this works is that any symbols across a winning payline, during the free spins, will be removed and the reels will roll down one position, replacing the missing symbols with a new one. If the replacement symbols trigger another win, the multiplier will increase another step. 2 consecutive wins will award a 2x multiplier to that winning line, 3 consecutive wins a 3x multiplier, and so on, up to 5x.
If the rolling replacements don’t reveal another winning line, the multiplier is reset to 1x and the free spins will continue. Note that the Rolling Reels feature does not substitute for the free spins. When the free spins are over, you’ll return back to the normal game, hopefully with some big wins!
Any further scatter bonus symbols will mean you can re-enter any of the 4 games, with the most lucrative being Thor’s.
Thunderstruck II Slot RTP
Thunderstruck 2’s RTP (return to player) is 96.65%. What does this mean? Mathematically speaking, this means the house edge is 3.35%, and for every £100 you spin through you might expect to see a return of £96.65.
There isn’t a defined amount of time that this rate will be experienced, which can be both good and bad for you. There’s a chance that you’ll load a slot, hit the Valkyrie bonus feature straight away and walk away with a nice win. There’s also a chance that you’ll spin the reel 10 times in a row at the maximum bet and win nothing.
How to Win on Thunderstruck 2
Since there is a choice to be made when The Great Hall of Spins opens each time, always choose the character that you’ve unlocked furthest to the right. This will ensure you get access to the highest amount of free spins and more lucrative features.
Additionally, you can define your own strategy before you sit down for a slot session:
The very best way to swing the odds in your favour when it comes to gambling is to leverage a casino’s bonus offer. This will reduce the amount you risk of your own bank, if any. This is the case with a no deposit welcome offer where you can utilise the casino’s free bonus money or spins.
Thunderstruck II Slot: Casino Deal’s Thoughts?
Our initial impression of the graphics faded the more we played Thunderstruck 2 and moved towards the bonus game feature. We particularly liked how the art style changed when moving through the characters of Valkyrie, Loki, Odin and Thor.
Using Norse mythology is very niche and has proven to be a good choice by Microgaming; they’re appealing to a huge fan audience and leveraging the Marvel franchise to good effect, without needing the rights from Marvel specifically.
Despite a lack of a jackpot feature, The Great Hall of Spins definitely makes up for this. The generous amount of free spins, the chance to trigger further free spins and the large multipliers can lead to some very big wins. The coin payouts for winning lines in the normal game are decent too. This means that VIP high rollers might be swayed towards the game, although the majority will favour progressive jackpot slots.
The RTP of 96.65% sits in the middle of the road for us. It’s not shamefully low but it’s also not high enough to warrant using Thunderstruck 2, for wagering through a bonus offer. That being said, some fan favourites still choose it as their go-to for this purpose.
Overall, the Thunderstruck 2 slot is an engaging and well-designed game. One which we’re sure you’ll enjoy playing!
