Thunderstruck II in a Nutshell

Thunderstruck II is a hugely popular slot game in the Microgaming library and although it was released back in 2010, we have heard that very soon there will be a remastered version being released by Microgaming to update the graphics which is exciting news! This is a game with a Norse mythology theme and a huge free spins bonus round that has four different levels to work your way through. Plus, you can also look forward to a wild symbol and a randomly triggered feature that turns your reels wild. Thunderstruck II is a mobile-friendly slot game with a high RTP of 96.95% and you can get started playing today from as little as 30p per spin.

How to Play

How to Play Thunderstruck II in Four Simple Steps

It’s really easy to get started playing Thunderstruck II and here’s your step by step guide on how to do so.

  1. Use the Coin value button and the + and – buttons to set your coin value
  2. If you want to place the maximum bet, simply avoid the first step and hit the Bet Max button
  3. You can use the autoplay function to choose the number of spins you want and your bet per spin, then let the game play automatically. You can set up to 100 free spins on autoplay
  4. Once your bet is decided and placed, hit the SPIN button to send the reels tumbling

Gameplay

Gameplay, RTP and Variance

Thunderstruck II is a five-reel, three-row slot game with a massive 243 paylines. Players can place a bet from as little as 30p per spin and this rises to £15 per spin.

The RTP of this game is quite high compared to other slots at 96.65% and so you are more likely to stop playing and have a win on your hands. This is a high variance slot game, which means it’s designed to payout large sums fairly infrequently.

Bonus

Bonus Features

There are three special features in the Thunderstruck II slot game including a wild symbol, wild storm feature and a free spins bonus round.

The Thunderstruck II game logo is the wild symbol and this will substitute for other symbols on the reels to form new winning combinations and create big cash prizes.

The wild storm feature is triggered at random but you won’t be able to miss it as Thor’s lightning bolts will reign down from the sky to turn as many as five of your reels into wild reels.

This can potentially be an extremely lucrative round as players can win up to a whopping 8,100x their stake.

The main highlight of playing Thunderstruck II is The Great Hall of Spins which is a free spins bonus round. There are four parts to this free spins round and they act as levels, so the longer you play, the more chances you will have to climb through them. Thor’s hammer is the scatter symbol and landing three or more of these will trigger the first round of four. You will play at this first level for the first four triggers and then on the fifth trigger, you will move to the following round. This continues to happen until you make it to level four

  • Level One – Valkyrie is the first level which you play from the first to the fourth trigger. In this round, players are awarded 10 free spins and a 5x multiplier. You can win up to 1,383x your stake per spin here and you can retrigger the round, giving your 20 free spins in total
  • Level Two – Loki is the second level which you can play from the fifth to the ninth trigger. In this round, players are awarded 15 free spins and a wild magic feature. Wild magic symbols can land on your third reel, transform into wild symbols and award you bigger cash prize by forming more winning combos. If you land extra scatter symbols on your reels you can get up to a further four free spins and you can win up to 8,100x your stake per spin here
  • Level Three – Odin is the third level which you can play from the tenth to fourteenth triggers. In this round, players are awarded 20 free spins plus the wild raven feature. Watch out for Odin’s ravens on the reels as they will turn symbols into multipliers of 2x or 3x and can even turn them into a 6x multiplier if two ravens land on the reels. You can win up to 3,320x your stake per spins in this round
  • Level Four – Thor is the fourth and final level where you enter The Great Hall and you can play this round from the fifteenth trigger onwards. In this round, players will be awarded 25 free spins and a rolling reel feature. Your wins here will receive a multiplier which starts at 2x and increases by 1x each time you get a winning combo. This will reach a maximum multiplier of 5x

Mobile

Playing Thunderstruck II on Mobile

If you want to play Thunderstruck II on your iOS or Android device, you can easily do so as this game is mobile-optimised. The controls and graphics adapt perfectly to fit both mobile and tablet screens, so you don’t have to worry about making any compromises when you take your gameplay on the go.

Presentation

Design, sound and graphics

Thunderstruck II is a decade old and while the graphics are not as sharp as some of the newer slot games on the market, they’re still good and it doesn’t seem to put off any players from spinning its reels! This slot game has a Norse mythology theme and is centred around the gods that the Vikings used to worship. Behind the reels is a dark blue background and there is a border around your reels with a cool Celtic design. On the reels, the high-value symbols are represented by the different Norse gods including Thor, Odin, Loki and Valkyrie. The lower value symbols are represented by your standard playing card symbols. Other symbols on the reels include Viking longships and the city of Asgard. As you spin the reels, you will hear the thunder rumbling and epic battle music plays when the bonus features are triggered.

Our Verdict

What We Think

Thunderstruck II has long been one of the most popular slot games online and it doesn’t appear to be going anywhere anytime soon with a newly remastered version on its way that will update any issues with slightly outdated graphics. Players who like epic slot games will love the music and Norse mythology theme of this game. Plus, with wild reels and a massive free spins bonus round with four levels and the chance to win up to 8,100x your stake, it is easy to see why this game has been a top choice for players over the past 10 years.
