Gameplay, RTP and Variance

8/10

This is a five-reel, three-row and 243-payline slot game that players can experience from as little as $0.30 to £15 per spin. 

Thunderstruck II has an RTP of 96.65% which is above the slot average of 96%. As this is a high variance slot game, it’s designed to pay out infrequently and has the potential to offer large payouts.

In the base game, the highest value symbol on the reels is the bonus scatter symbol and this will pay out 200x your stake for five landing in a winning combo on the reels.

Licence and Audit

Thunderstruck II is part of the world renowned collection of slots from Microgaming. Peace of mind comes from the fact that this top software provider holds a license from the UK Gambling Commission as well as the Malta Gaming Authority. You can trust the randomness and fairness of Thunderstruck II as Microgaming is a founding member of the world-class auditor eCogra and their games are regularly tested. 

Bonus Features

8/10

Thunderstruck II has three special features – a wild symbol, a wild storm feature and a free spins bonus feature. 

The wild symbol is the Thunderstruck II game logo and this will act as your standard wild by replacing other symbols on the reels to help form new winning combinations and award bigger cash prizes. 

A randomly triggered, exciting part of this slot game is the wild storm feature. When Thor sends lightning bolts down onto your reels, you’ll know this feature has begun. Up to five of your reels can be transformed into wild reels and award wins of up to a massive 8,100x your stake. 

The big bonus feature in Thunderstruck II is the free spins round which is aptly named the Great Hall of Spins. Players will start on level one and then work their way through the four levels as they play. All you need to do is land the Thor hammer scatter symbol on your reels three or more times to enter the first level of the free spins. 

  1. Valkyrie Level One – you’ll play in this level from the first free spins trigger to the fourth. Ten free spins are awarded, plus a 5x multiplier. Retriggers are possible to award you 20 free spins altogether, and there’s the chance to win up to 1,383x your stake.
  2. Loki Level Two – you’ll play in this level from the fifth free spins trigger to the ninth. There are 15 free spins awarded alongside the wild magic feature. On the third reel, wild magic symbols can appear which act as normal wild symbols to help form more winning combos and award further cash prizes of up to 8,100x your stake. Players can get an additional four free spins by landing more scatter symbols.
  3. Odin Level Three – you’ll play in this level from the 10th free spins trigger to the 14th. Here, 20 free spins are awarded along with the wild raven feature. Ravens are sent onto the reels by the mighty Odin to transform symbols into multipliers of between 2x and 3x. If you get more than one raven landing on the reels, you can get a multiplier awarded of up to 6x. Wins of up to 3,320x are up for grabs.
  4. Thor Level Four – you’ll play in this round from the 15th trigger onwards and will receive 25 free spins plus an increasing multiplier. The multiplier starts at 2x and goes up each time you get a winning combo by 1x up to a maximum of 5x. Players can win up to 1,383x their stake in this round.

Mobile and Tablet Experience

8/10

Thunderstruck II is a mobile-friendly slot game that you can access anytime, anywhere, straight from your mobile or tablet device. As the game is designed using HMTL5 technology, it adapts to fit the size of your screen. Both iOS and Android devices will support Thunderstruck II. 

How Does it Compare to Other Microgaming Titles?

Microgaming has one of the biggest collections of games of any software provider and, while Thunderstruck II is in its top 10, the company also has a wide range of other hugely popular slot games that have achieved iconic status in the online gaming world.

One of the most spun slot games from Microgaming has to be Mega Moolah. This title has been around for more than 15 years and is still as popular today as it was when it was first released. This game has a great African savannah theme and you’ll spot lots of safari animals on your reels including gazelles, lions and zebras. This is quite a simple slot game compared to Thunderstruck II as it doesn’t have the same big bonus features to enjoy. However, it does offer the chance to win four progressive jackpots. Players who manage to win the Mega Jackpot can take home a massive win into the millions of dollars. So, if you want to play for the big bucks, Mega Moolah may be a better option for you, and you can spin its reels from just $0.25.

Another very popular slot game from Microgaming is Immortal Romance. This vampire-themed title has a jackpot version, or you can play the original with five reels, three rows and 243 ways to win. This slot game is very similar to Thunderstruck II and uses the same engine. The highlight is a free spins bonus round where you’ll work through four levels based on each of the characters from the reels. In this game, you can win up to 12,150x your stake, which is more than what’s up for grabs in Thunderstruck II. 

How Does it Compare to Other Slots on the Market?

Thunderstruck II is no doubt one of the most popular Norse mythology slot games available on the market today, but there are many other fantastic slots with a similar theme that you may want to consider playing. 

If you like Thunderstruck’s theme but want to play for bigger jackpot prizes, you may want to try spinning Hall of Gods. This is a five-reel and 20-payline slot game from NetEnt that features expanding wilds, a picking game and a free spins bonus round with big multipliers. The highlight is the array of progressive jackpots: players can try for the mini, midi or mega jackpots, with the latter starting at a whopping $500,000. Players can spin the reels of this game from as little as $0.20 per spin.

If you love Megaways slot games and also want to play a slot with a Norse mythology theme, Odin’s Infinity Reels Megaways from ReelPlay and Big Time Gaming may be the better option for you. This game provides the opportunity for infinite reels alongside gorgeous, high-quality graphics. There are some great bonus features in this game, too. These include a wild symbol, increasing multipliers, a jackpot feature and a free spins bonus round that combines free spins with an increasing multiplier to award big cash prizes of up to a massive 20,000x your total stake. This is more than double the maximum win available in Thunderstruck II. You can spin its reels from $0.30. 

Design, Graphics and Sound

6/10

Thunderstruck II is not a new game to the market and so the graphics once appeared quite dated when compared to newer slot games. The good news is that Microgaming have updated and remastered the graphics to give it a more modern edge. On the reels, the lower value symbols are the standard playing card symbols 9, 10, A, J, Q and K, while the higher value symbols all relate to the theme. You’ll spot many legendary gods including Valkyrie, Loki, Odin and the god of thunder himself, Thor. The soundtrack to this game is fantastic as grand battle music plays during the bonus features, and you’ll also hear the sounds of thunder as Thor smashes his hammer.
