Valhalla Saga: Thunder of Thor Review

Playable on 5 reels, 3 rows and 20 paylines, Thunder of Thor is the first Norse-themed release from Jelly and Yggdrasil in their new Valhalla Saga series. As a flagship slot, it offers some intriguing gameplay, fuelled by the unique PowerLinks mechanic where scatters can increase your wins and trigger jackpots. Also, in this instalment, you’re invited to witness first-hand the powers of the enchanted war-hammer. Often seen as a destructive weapon, here it can be used as a powerful instrument to awaken wild multipliers of up to 100x and give you wins of up to 10,000x your stake during free games. But, don’t just plunge head-first into the unexplored depths of this Viking saga. Prepare for your new epic adventure with our full slot review below first!

Valhalla Saga: Thunder of Thor Bonus Features

Thunder of Thor is powered with one main bonus feature and a couple of random modifiers, helping you to either get into the bonus round or benefit from multipliers. While both play a vital role in helping you win bigger, the game’s biggest wins, including jackpots, are hidden within the special frames feature running on the PowerLinkS mechanism. Upgrading those frames or zones is the only way to reach the game’s max potential. Non-UK players can also utilise the Bonus Buy feature, which can be purchased at 60x and guarantees an instant entry into the free spins bonus round. Let’s inspect slot machine features in detail!


Throughout the game, the mighty Thor’s hammer wilds can substitute for all paying symbols except scatters, but in the Thunder of Thor modifier round, they can also appear as multipliers.


A golden Norse symbol of thunder and lightning serves as a scatter, but you’ll need no less than 5 of these to show up anywhere on the reels to activate the free games bonus round.

Bonus Respins

There’s a possibility to activate the free games bonus with the help of the bonus respin feature, should you find yourself with just 4 scatters in the base game. If you’re lucky the reels will respin, giving you an additional chance at landing the scatter needed for triggering the bonus round.

Thunder of Thor Modifier Feature

Triggered randomly on any spin, the Thunder of Thor modifier creates new wilds with multipliers ranging between 2x, 5x, 10x, 20x, 50x and 100x.

Free Spins

Activated with 5 scatters, the free spins bonus round awards 5 free games with each triggering scatter leaving a special frame or zone behind it. The frames remain sticky and guarantee prizes at the end of the bonus round. Watch out for any additional scatters landing within these zones. If that happens, the PowerLinks mechanic will kick in to upgrade the guaranteed rewards respectively:

  • Wooden zone (1 scatter hit) awards 1x – 5x.
  • Bronze zone (2 scatter hits) awards 10x – 25x/Mini.
  • Silver zone (3 scatter hits) awards 30x – 100x/Minor.
  • Gold zone (4 scatter hits) awards 125x – 250x/Major.
  • Fire zone (5 scatter hits) awards 400x – 1,000x/Mega.

Valhalla Saga: Thunder of Thor Jackpot

As a jackpot slot, Valhalla Saga: Thunder of Thor contains three jackpots, Mini, Minor, Major and Mega, worth 25x, 100x, 250x and 1,000x your stake respectively. These can only be won during the free spins game from the special zones mentioned above. The good news is that the wins don’t stop with the Mega jackpot worth 1,000x your bet. They can increase through multipliers and reach up to 10,000x your stake.

RTP and Volatility

Although it has plenty of random features to get you through hot and cold spells here, don’t underestimate the game’s high volatility. Landing big wins won’t be easy. Don’t rely too much on the RTP rate either – it’s set to 95.90%, which is just below the current industry-average.
