Thunderstruck II Details and Wager Limits

Thunderstruck II is a medium volatility slot. It means that you can expect a reasonable amount of smaller wins, while you fight your way through to one of the lucrative bonus games. The game is played on a classic 5x3 matrix. You have most probably played this kind of game before, so it all should be pretty straightforward. We liked the fact that this slot features the industry-leading 243 ways to win technology. It's always a good thing to have more paylines, as it makes the game more exciting. But note that both ways to win option is not included, meaning that winning paylines will be calculated only from left to right.  

Autoplay on this slot is pretty basic. There is no option to set when it should pause, which is a small minus to Thunderstruck II. You can set the number of spins in the range of between 10 and a 100. Also, note that there is a quick spin option available, for the players who want to cut the waiting time between spins. Thunderstruck II is a great game for the players on the budget. You can set the coin size to as little as 0.01. The biggest coin size is 0.05, which adds up to the max bet of 15 coins per spin.

The game is sometimes referred to as Thunderstruck 2 slot. This is mostly down to language barriers and translations. Rest assured though that these are in fact the same game. Those who opt to play Thunderstruck 2 slot are in for the same details and layout we just mentioned.

Thunderstruck II RTP

This game has a pretty average RTP of 96.6%. It's not that bad at all, but if you are searching for a high RTP game, there are plenty of much better options out there. Keep in mind that the return to player rate is calculated over a huge number of spins, so it makes a difference only if you are playing for a long, long time. It's a mathematical model, so the high RTP doesn't mean that you'll start scoring wins right away, or vice-versa. To cut a long story short, if you are not planning to play thousands of spins on a single slot, don't get too caught up with the RTP rates. It's also good to point out that Thunderstruck II slot RTP is actually higher than the original Thunderstruck slot game released by Micrograming.

Thunderstruck II Audio and Design Features - A Game Design Masterpiece 

Don’t let the name fool you, this isn’t another one of those pop culture themed slot like NetEnt’s Guns N’ Roses. It’s actually inspired by Nordic Mythology; think Hall of Gods without the progressives. No ACDC in this one! You'll still find a lot of recognisable character on the reels. These include Thor, Loki and Odin, as well as Valkyries, battleships and portraits of Asgard. Lower value signs are classic card symbols. But they are perfectly designed to fit the game. The whole slot looks very dark and dramatic. The background seems like it's made of stone and iron, which just adds up to the atmosphere. Graphics look a bit dated, but it's no surprise since this game is released almost a decade ago. However, we can't deny that the Microgaming did a spectacular job designing this slot, as it still looks mysterious and very appealing. 

Audio effects are one of the best things about this game. Music is so melodic and beautiful that it will make you feel like you're in one of a Nordic fairy-tales. There will be more great sound effects every time you get the winning payline. For example, if you land any bonus symbol, you'll hear the dramatic sound of metal hitting a stone. All the audio effects flawlessly fit the game, making Thunderstruck II a real feast for both eyes and ears. Note that you can enjoy all of this directly from your smartphone or tablet. Thunderstruck II is fully optimised for all kinds of devices and screen sizes, making it a perfect slot for a quick game on the move.

Bonus Features and Games in Thunderstruck II Slot

You'll be surprised how many bonus features are in this slot. Apart from the wild and scatter symbols, there are several other lucrative bonus games. But lets' start from the beginning. The wild symbol is the game logo, and it does two important things: 

  • It can substitute every symbol except scatter
  • The wild symbol will double the prizes from any winning payline it is part of

We have really liked the multiplier feature of the wild symbol. It adds real value to the whole game, so hopefully, the other providers will follow this excellent practice by Microgaming. 

Scatter symbol is Thor's Hammer. If you get two of them, there will be a cash prize waiting for you. But, if you find three or more scatter symbols, you'll enter Thunderstruck II main bonus feature named The Great Hall of Spins. If you want to learn more on this subject, scroll down and keep reading. 

The Great Hall of Spins Bonus Feature

After you gather three or more Thor's Hammers, you'll be invited to enter The Great Hall of Spins. The music and the background will change, while the narrator explains how this fantastic feature works. You'll be able to choose one of four games named after main characters - Valkyrie, Loki, Odin and Thor. However, not all games will be available straight away. As you play the game and collect scatters, you'll gain experience and get to play more lucrative bonus games. This is how it works: 

  • The Valkyrie Bonus Game - It's the first game you'll be able to play. Valkyrie brings you ten free spins and 5x multiplier. You can retrigger free spins if you get another three scatter symbols during the bonus round. 
  • The Loki Bonus Game - Game is available after you trigger a bonus game for the fifth time. It will bring you 15 free spins and a special Wild Magic symbol that can turn up to fourteen regular symbols into wilds. You can retrigger free spins by landing 3 or more scatters.
  • The Odin Bonus game - This bonus will be available after tenth time in. Odin game will get you 20 spins and a Wild Raven symbol that can transform random signs into wild multipliers. This way you can get up to 6x multiplier. However, it's not possible to retrigger free spins. 
  • The Thor Bonus Game - You can choose Thor game after the fifteenth time into The Great Hall of Spins. It will bring you 25 free spins and a Rolling Reels feature. During this feature, all winning symbols will be removed, and the symbols above will shift downside to fill the spots, giving you the opportunity for extra winnings. Each time this happens, you'll get a multiplier, stacking up to 5x. But, as with the Odin game, you can't retrigger the free spin feature.  

Wild Storm Bonus Game

This is another great bonus feature, but unlike The Great Hall of Spins, it's not triggered by any particular symbol. You'll never know when the Wild Storm Bonus will start. But once it does, you'll be well aware. The screen will become darker, and the stormy clouds will tower the reels. While dramatic music plays, up to 5 reels will become wholly stacked with wilds, giving you the opportunity for some serious winnings. Not that the number of reels that will become wild reels is determined randomly. We liked this feature because you never know when it will occur, so you'll always be on the edge of your set. Also, it can bring you a lot of money, especially if you are lucky enough to get 4 or 5 wild reels. 

Thunderstruck II Paytable Achievements 

This is a nice little feature, that can help you keep track of your game progress. Every time you reach every possible combo for a particular symbol, that sign will be highlighted on the game's paytable. There is no special prize for getting the achievement, apart from knowing that you are slowly becoming a Thunderstruck II veteran. Note that your progress will be saved even after you log out of the game, but wins with the wilds and free spins will not be logged as achievements.  

Thunderstruck II Slot Review Summary - Even Better than the Prequel! 

There is no question about it, Thunderstruck II is one of the best slot games you'll ever find. It features a fantastic range of bonus games, which includes wilds, multipliers, free spins, special bonus games and so on. Not many slots have features like this, so Thunderstruck II is definitely worthy of a second look. The only downside to this slot can be the fact that it visually looks a bit old, but even that nicely fits the game theme. This Microgaming slot is a true masterpiece, so there is no reason not to visit some of the online casinos from the list at the beginning of our Thunderstruck II slot review and try this awesome game.
