Yggdrasil already has a strong line-up of viking video slots, including the ‘Vikings Go’ series – but Thunder of Thor is setting sail to become its own legend, as the first of a new three game Valhalla Saga compilation. The series is being created with a vision of being an ‘ultra-epic Viking series like no other’, with the first game, whirling you into the Thunder of Thor. The follow-up games will feature two other famous vikings: Loki and Odin! As the launch game in the series, Thunder of Thor needs to make a strong impact, and it does so via the exclusive new PowerLinks™ bonus, combined with rich arcade slot graphics and tons of winning action in a typical session. The themed slotscape is seeded with prize zones that can upgrade to bonus rounds and huge 100X wild multipliers, while the  Thunder of Thor modifier can create wild wins up to 100X! Ultimately, Thunder of Thor, pays homage to the power of this viking legend’s hammer, and heralds the start of the much anticipated Valhalla Saga series from Yggdrasil.

Thunder of Thor slot has 20 paylines, an RTP of 95.90%, high volatility and average hit frequency of 32.84%. 

As you can see, this spinner has a high average hit rate, but is also pretty volatile – so what does this mean in reality? Typically, it means the game can go through hot and cold runs, with the potential for some really lucky spin clusters! This game doesn’t consistently fire-out wins at the theoretical average of 32.84% – it’s often more likely to be below or above this level – with the upside having serious power when hot runs are encountered. This makes Thunder of Thor slot ideal for players who like excitement and the potential to win big returns (relative to their bet size).

When it comes to betting, you can play Thunder of Thor slot with bets ranging from €0.20 to €40.

Thunder of Thor slot machine also has a Bonus Buy option, which costs 60X the standard bet, but instantly triggers the potentially powerful bonus round.

Payouts in Thunder of Thor

Thunder of Thor slot has a line-up of nine symbols that payout for landing a standard 3-5 icons: Thor, Viking ship, Thor’s Axe, Golden chalice, A, K, Q, J and 10. As illustrated in the Thunder of Thor paytable below, wins can range from X0.2 to X25 the triggering bet, creating a large range of potential base game wins. The basic payout range on the minimum €0.20 bet, is €0.04 to €5, while on the maximum bet of €40, it’s €8 to €1,000.

While the base game wins in Thunder of Thor slot machine are fairly standard, you can potentially send wins soaring to Valhalla, if you get enough luck on these bonus features. With a maximum win up to X10,000 the triggering bet, the game can theoretically payout between €2,500 and €400,000, depending on your level.


When you play at the best Thunder of Thor slot sites, you can try and trigger the game’s powerful bonus features – Bonus Respins, Free Games and Hammer of Thor! Here’s an insight into Thunder of Thor’s slot bonuses:


If you trigger four scatters on reels 1-4, but the fifth scatter isn’t activated, a Bonus Respin can be awarded, with the animated Thor’s Hammer smashing the slot screen! The Bonus Respin has the potential to bring in another Scatter symbol and trigger the Free Games.


The Free Games round unleashes the new PowerLinks™ bonus mechanic. The Free Games are launched when five or more scatters land on the reels and leave an imprint on the screen. The bonus gives you five Free Games, with any scatter symbol landing in a previously imprinted location, further boosting the payout potential. Wins in the Free Games are revealed at the end of the round and paid as a multiplier of the original bet.


A special Hammer of Thor modifier can be triggered on any spin, amidst a burst of animated action and sounds. Any wild can become either a x2, x5, x10, x50 or x100! wild multiplier. This activates huge potential wins and is one of they top reasons why this game is getting a lot of attention.

Overall, Thunder of Thor video slot has some exciting new bonus features, creating exciting visuals and the potential for some nice wins if you get enough luck. Due to the game’s volatility, buying the bonus for x60 is an option, but be sure to consider your budget before giving it a go.
