Theme and Graphics

Thunderstruck II is much darker and dramatic in appearance than the original game. It’s set against a dark steel-grey background edged with Nordic design borders that appear to have been engraved into the metal.


The game’s music is dark and brooding and wouldn’t sound out of place in a Hollywood blockbuster about Viking gods.

It’s fairly relaxing and subtle and won’t distract from your gameplay; having said that, it’s fairly atmospheric and fits in well with the epic game that this has become.

How to Play

It’s very simple to play Thunderstruck II and you don’t need to have any knowledge of slots games or how they work in order to get started:

  • To change your bet, simply used the plus and minus buttons displayed underneath the coin amount. You can then change the number of coins you bet.
  • If you want to bet the maximum available amount, hit the Bet Max button. This will automatically set your bet size to the maximum number of coins.

How to Win

There are 243 ways to win and these 243 ways are always active. There is no way to increase or decrease the number of paylines or win ways.

If you are lucky enough to land a multiple winning combo, featuring different symbols, you will be paid out for each combo. If you land a multiple winning combo with more than one win from the same symbol, only the highest winning combo for that symbol will be paid out.

Free Spins

Thunderstruck II has a total of four free spins games. These are accessed from the Great Hall of Spins feature, which is triggered when you land three or more bonus hammer symbols anywhere across the reels.

If you are lucky enough to trigger the Great Hall of Spins feature five times, a new free spins game will be opened up and you’ll be able to select this in future free spins sessions.

The following options are available:

The Valkyrie bonus game

n the Valkyrie game, you will get 10 free spins. Free spins can be retriggered during the free spins game by landing three or more bonus hammer symbols anywhere on the reels. Any wins you land during the Valkyrie game will be multiplied by five.

The Loki bonus game

The Loki game awards you a total of 15 free spins. In the Loki game, you will see the Wild Magic symbol. This special symbol appears on reel four - the central reel - in random spins.

The Odin bonus game

The Odin game rewards you with an incredible 20 free spins. The special feature in this game is the Wild Raven symbol. It transforms symbols at random into wild multipliers.

You will receive up to a 6x multiplier on winning spins, paving the way for some fantastic prizes. Unlike the previous free spins games, it is not possible to retrigger the free spins if you are playing the Odin game.

The Thor bonus game

The Thor game is the fourth free spins game, and by the time this is unlocked, you will be able to choose from all four games each time you enter the Great Hall of Spins.

The Thor game rewards you with an incredible 25 free spins and has a special Rolling Reels feature. All winning symbols will be removed if they form part of a winning combo - after you’ve received your payout of course.

During the Thor game, you will receive a multiplier for every Rolling Reel. This multiplier increases by one with each consecutive win, up to a maximum of 5x.

As with the Odin game, it is not possible to retrigger the free spins while you’re playing the Thor game.

Wild Storm Bonus

As well as the Great Hall of Spins, there is another thrilling special feature that pops up at random while you’re playing the base game. The Wild Storm bonus game can be triggered on any spin, meaning you will never know when it might appear!

The entire set of reels will become wilds, and up to all five - the number of reels affected will vary and is determined at random - will become huge expanded wilds. This can be an extremely lucrative feature, especially if you’re lucky enough to have several reels turn wild at once.

The scatter symbol and the regular wild symbol will not appear during the Wild Storm feature, so you won’t be able to trigger free games during this feature, or receive any bet multipliers.

Other games like Thunderstruck II

If you’ve enjoyed playing Thunderstruck II but fancy a change and are looking for similar games, the following list might help you.


This is the game Thunderstruck II was launched as a sequel to and has a similar feel, but far fewer paylines and special features. You can read more about this game at the start of this article. Many casinos - although by no means all - that offer Thunderstruck II will also offer Thunderstruck, and vice versa.

Immortal Romance

This game has a very different theme from Thunderstruck II, but the gameplay and special features are similar, as are the sound effects. It is based on a glamorous and attractive looking young vampire, and definitely has a feel of the Twilight series of movies about it.

You’ll notice the paylines are similar to those of Thunderstruck II, and wilds act in the same way, as do the game’s scatters. You will also notice there is a randomly triggered special wild feature that works in the same way as Thunderstruck II's Wild Storm feature.

When it comes to free spins, they are triggered by three or more bonus symbols, just like the entrance to the Great Hall of Spins. You will receive a choice of four different free spins games, all with different numbers of spins and different special features and retriggering rules. Immortal Romance is a cult favourite among gamers, much like Thunderstruck II, and if you love one, the chances are you’ll enjoy the other as well.

Game of Thrones

Another game from the same developers, this also has a feel of Thunderstruck II. It has 243 paylines and has some great special features. The scatter symbol rewards you with a cash prize when you land two or more, and three or more will trigger the free spins.

As with Thunderstruck II and Immortal Romance, you will have several free spins games to choose from. The main difference here is that in Game of Thrones, you will have access to all of the free spins games from the start. There is no need to unlock the games here so you can choose which one you like the look of right away.

While the game is obviously based on the books and hugely successful TV series of the same name, you certainly do not need to be a fan of either in order to enjoy this exciting slots game.

Lara Croft Temples and Tombs

Lara Croft Temples and Tomb is yet another thrilling Microgaming-powered online slot. Like Thunderstruck II, the game has a 243 ways to win format that offers players plenty of generous winning potential whenever they spin the reels.

The game also comes equipped with Rolling Reels, which allow you to trigger multiple winning combinations on a single spin, as winning symbols are removed and replaced with new ones. As this happens, you earn multipliers that increase with each roll. The game also has a generous free spins round and three jackpots attached to it.
