Thunderstruck II Demo Mode / Play Free

You can get a grip of the game in demo mode at a trusted casino, but if you want to have the chance to make real rewards, you should play with real money. Our top recommendation where you can do that would be the Casimba casino, where you can play a ton of other stunning games, as well. You can join with a couple of clicks and play both on-the-go and desktop, hassle-free. Casimba is a trustworthy casino, which treats its players fairly, and gives you every opportunity to have fun.

Get Acquired With Thunderstruck II

Enjoy this Scandinavian-themed slot to the fullest, with high-paying bonus features and exciting bonuses waiting for you on each level. Thunderstruck II is not the most modern when it comes to graphics, but that will not matter once you find out the enormous winning potential it holds. You will be constantly thrilled and excited throughout the whole gaming process.

Thunderstruck II is obviously a sequel of the slot with the same name, which happened to be extremely successful and popular. Thunderstruck II was launched 7 years in 2010 by Microgaming. Sequels are rarely better, but this one is definitely one of those cases. On first look, the slot looks similar to the original, but once you start playing, you will realize how much better it is. It’s an updated version with some thrilling new features and a possible win of 8000 times your bet. This slot is a little more modern and feels more serious and heavier. The RTP of the slot is 96.65% and it has medium volatility. You will be able to find all the Nordic gods in the face of Thor, Loki, Odin and Valkyrie.

Multi-Level Bonus Features And Overall Gameplay

Thunderstruck II has a bet range of 0.30 to 60.00 for all lines covered. There are 243 ways of possible wins with only the highest being paid. The reels are 5 by 3 and the highest possible win is 8000x your total bet. The main and most exciting feature for the slot is The Great Hall of Spins. You can trigger it with 3 or more Scatter symbols. After enabling the feature, you get 4 levels for free spins to pick from. Each level is unlocked after triggering the feature a certain amount of times.

The first level is with Valkyrie with 10 free spins multiplied by 5. The second level is with Loki for 15 spins and a wild magic feature. The next level is with Odin for 20 spins and a wild raven feature. The last level includes Thor and grants you 25 free spins as well as a rolling reels feature. There is also a Wildstorm feature that gets triggered randomly and gives you 1 to 5 reels full of wilds. If you get all 5 reels full of wilds, you will get your bet multiplied by 8000.

Thunderstruck II Has Improved Design and Graphics

The slot has a very dramatic and a lot darker design in comparison to the cartoony style of the original slot. The background of the game matches one of the reels and you can find Nordic details on the frame of the reels themselves. The music for the game adds to the dramatic atmosphere and the bland dark background makes the symbols stand out more. The overall design definitely fits the epic gameplay. Thunderstruck II has been developed so that it can be accessed from any of your desktop or mobile devices. Regardless of the platform, you decide to play on, you will be promised the same thrilling experience.

All Nordic Gods As Big Winning Symbols

Most of the symbols for Thunderstruck II are themed. You should make sure to check them out before you get to hit the reels. We have decided to separate all symbols in different categories in order to better explain the importance and the power of each symbol that you are to encounter during the game.

Low-Paying Symbols


The bottom line of symbols are the 9 to Ace. Those are not very profitable, but if you roll high and manage to hit 5-of-a-kind, you will be able to win up to 5X your bet. Those symbols also happen to appear more often.

Medium-Paying Symbols


Next on the list are the viking ship and the Valhalla. These two symbols are themed and will bring more possibilities for generous wins. If you manage to land 5-of-a-kind, you will be able to multiply your bets by up to 10 times.

High-Paying Symbols


The highest paying regular symbols for Thunderstruck II are Valkyrie, Loki, Odin and Thor. If you end up hitting 5 of any of those you can get a bet multiplied by 11.6, 13.33, 15, or 16.66 respectively.

Special Symbols: For this slot you get a Scatter, which can pay you 200 times your bet if you land 5-of-a-kind, and a Wild represented by the logo of the game. 5 Wild will multiply your win by 33.33. The Wild will also substitute all regular symbols and double your win when doing that.

Thunderstruck II Slot – Editor’s Verdict

If you loved the original Thunderstruck, you will love Thunderstuck II even more. This slot is a lot more modern, and with better, well-designed bonus features, which also pay a lot better. You can win a fortune with any of the two main features. Having different levels to unlock, each one with better prizes, can have you hooked and playing for many hours. Thunderstruck is highly recommended for so many good reasons. If you love a Nordic God-themed slot, then there will be nothing else you should worry about, as this slot has it all. The game is perfect for low and high rollers, and also available to all desktop and mobile platforms.
