Greetings, warrior! Are you up for an adventure? We might have the right one just for you! Fresh from the oven of the magnificent Red Tiger, here comes a heroic venture into the land of Norse gods. Grab a hammer! The rising star in the field of game manufacturing released this mighty 7x7 slot for all those who are eager to prove their worth in daring undertakings. Bust out your armor, the god of thunder is waiting!

Scandinavian Insignia

Daring undertakings are usually found amidst ruins or desolate caves. So is the case with this particular one. Red Tiger creators placed this cluster slot among heavy standing stones in the frosty Nordic winter. The suspenseful atmosphere is amplified with some epic music playing in the background during the playtime. 

The 7 reels are made of stone as well, and the most prominent detail is the central Free Spins engraved on a 3x3 block of stone. Four runes carved into stone form a set of lower-value symbols, while four battle masks constitute a set with higher worth. The highest paying symbol is the hammer belonging to Thor. There’s also the Wild symbol which can substitute any other symbol on the reels.

Dangerous Exploits

The cascading mechanism is employed for the reels. To score a win, you’ll need to land a cluster of five or more identical runes or masks. Each hit will result in the explosion of the winning cluster, and more tiles will fall into the void places. 

Free Spins are hidden beneath the stone tiles in the center. To free them, you’ll have to hit winning combinations directly next to the tiles. That way, the stone will break tile by tile, and eventually yield some mighty free spins for you. Honestly, it may be easier said than done, but Thor is a merciful God – he’ll come to your aid from time to time and wield his Mjolnir. He can either clear a whole row and column by replacing everything with identical symbols, or he can release the thunder which will hit 5 random tiles and transform them into wilds. Both cases are random occurrences that can bring you multiple awards!

Once you remove all the blocks from the centre, you will be able to choose between two different versions of  Free Spins. The first is the Valhalla Free Spins where all regular symbols on the reels will be replaced with golden shields and blanks. The golden symbols will be locked in place once they fall down. When the round of free spins concludes, they’ll convert to bet multipliers for your total win in the round!

The other version is the Muspell Free Spins where the rules are the same as in the base game but the reels become devoid of lower-value symbols. Two extra features may appear – the Lava Shower and Lava Flow – which can either remove some symbols to activate a re-spin or trigger some winning clusters.

Only the Valiant Go to Valhalla

The good thing here is that you don’t have to be a real Viking to get there. All it takes is a little bit of playtime in this 96.10% RTP slot! 

The price of fame in this slot of high volatility starts at €0.20 and can go as high as €40 per spin. Luckily, Red Tiger casinos made sure to give you access to unlimited fun with mobile, tablet, and desktop availability of this epic game.
