Hammer of Thunder Slot Review

Slot game fans with a penchant for Nordic lore will find themselves delighted by Spadegaming’s Hammer of Thunder slot. Even those who’ve ventured into a certain superhero universe will be pleased to see Thor taking pride of place on this 6×6 grid slot. The epic battle between Thor and Loki is the background, but the real stars are all the fantastic features packed into the game!

Hammer of Thunder Slot Review

Players will find cascading reels that keep the winning combinations rolling in, as well as wild and scatter symbols, multipliers and free spins! The game has an above-average RTP of 96.89% and a huge betting range making it suitable for all types of players. 

Bolts of Excitement: Hammer of Thunder Features

The Nordic Gods are certainly benevolent in this mythical game, enthralling players with a feature-packed slot that packs a punch. More than 8 of any symbol on the reels will strike a winning combination. But, if that isn’t electrifying enough for you the cascading reels pump up the excitement even further and give you more chances to win.

The cascading feature means that winning combos will fall out of place to make way for more potential wins, this godly cycle continues until no new wins are on the reels. Aside from this, there are plenty of other great features on this slot such as the sticky wild Hammer of Thunder which triggers the respin feature and the free games feature.

Hammer of Thunder Free Games Feature

When 4 or more scatter symbols land on the reels you’ll be treated to the Hammer of Thunder free games feature which gives you 10 free spins. Any additional scatter symbols that appear on the reels during the game will award you a further 2 free spins on the counter. 

Hammer of Thunder Free Games Feature

The bonus multiplier begins at 1x and increases when a Hammer of Thunder symbol with a random multiplier forms a winning combination. The multipliers can be 1x, 2x, 3x or 5x and will accumulate and remain throughout the free game for a huge potential win. 

Nordic Icons: Hammer of Thunder Symbols

This slot is infused with unmistakable Norse gods and mythology, from the stunning backdrop of Asgard guarded by the imposing image of Thor. The symbols continue the theme beautifully, with Thor’s father, Odin, his wife, Sif and brother, Loki being the highest-paying symbols. 

Iconic Nordic tools and weapons are the next set of symbols, such as the axes and warhorn, followed by the lowest-paying symbols which are the A, Q, K. J and 10. Unsurprisingly, this godly game also delivers some unique and powerful symbols:

  • Scatter Symbols – 4 or more of these anywhere on the reels will instantly trigger the Free Game feature.
  • Wild Symbols – substitutes all symbols aside from the scatter and the mighty Hammer of Thunder itself.
  • Hammer of Thunder – this electrifying symbol acts as a sticky wild. It replaces all other symbols aside from the scatter and triggers a respin. The hammer remains in place on the grid until the winning combinations run out.

A Godly Triumph: Hammer of Thunder Max Win

The max win on Hammer of Thunder is a modest 285x, but this is offset by the chances that you have to reach it. The cascading reels mechanic, plus the accumulating multipliers in the Free Game feature give you ample chance to pump up your bankroll. 

Gambling with the Gods: RTP & Volatility

Hammer of Thunder stays in the middle range for variance, meaning that both the frequency and amount of payouts will be moderate. This is often preferable for many slot enthusiasts as it strikes a middle ground. The return to player (RTP) value isn’t going to create storms, but it’s above average at 96.98% which I’m more than happy with. 

Fortunes Strike with Hammer of Thunder Bonuses

If you really want to feel the force of Thor, you’ll be looking out for the Hammer of Thunder to strike on the reels in this slot. You only need one to land on the reels for a huge chain reaction that triggers a bonus spin. For another lucrative bonus feature, you’ll need to look out for 4 or more scatter symbols on the grid to activate the free games round. 

Hammer of Thunder Respin Feature

Landing 4 or more scatter symbols on the reels will award players with 10 free spins in the base game. Each additional scatter that lands during the bonus round, will give you another 2 free spins.

Thor’s Rewards: Benefits of Playing Hammer of Thunder

Spadegaming’s Hammer of Thunder has some electrifying perks that will keep you holding on through the storm. It’s stunning graphics and varied features are just some of the main benefits I found when playing through the game.

There’s something about getting a winning combination and then SLAM, they cascade off the reels and make way for even more winning chances. It’s so satisfying and it keeps the game interesting.

Gods and mythical wonders might not be the most original slot theme, but Spadegaming have managed to do the Nordic god justice in this Thor-inspired slot. The animations and graphics are just enough to enchant without being distracting.

Who doesn’t like to feel like they actually have a good chance of returning their wagers. Of course, it’s not always possible with these games of luck. But, Hammer of Thunders RTP of 96.98% is almost as good as it can get.

It might not be the most feature-packed game I’ve reviewed, but those that are offered in this game have been integrated perfectly into the theme and slot. The bonus symbols which trigger respins and free spins, as well as the multipliers.

Harnessing the Storm: Tips & Tricks for Hammer of Thunder Slot

While you might not be able to harness the elements of Hammer of Thunder with the finesse of Thor, there are still some strategies you can try to enhance your game. Of course, always keep in mind that slots are based on random number generators (RNG), so it’s not entirely possible to predict outcomes. But, you can be tactical with your betting and gameplay to maximise winning potential.

  • Try the demo version of the game before betting real money.
  • Having a strict betting limit in place is helpful.
  • Keeping track of the time you play is also essential. 
  • Use the Auto Spin to stick to a set betting limit for a number of spins.
  • Input your desired winning threshold and losing limit.
  • When playing manually, adjust your bet amount up or down according to the winning cycle. 

Embracing the Thunder: My Experience with Hammer of Thunder Slot

While I certainly enjoyed the visual aspect of this Spadegaming addition, particularly the animations of the features in the slot, the medium volatility just didn’t quite hit for me. As I lean more towards the higher volatility slots, I found that this one just wasn’t hammering out those less frequent, yet larger wins. 

That being said, the features and gameplay are well done, so for players who don’t mind a more balanced slot game it’s a fantastic option.
