Wow! Where shall I start? Let me kick off with the tremendous win potential. The max win is a staggering 30,000x, and indeed, it tops the list of the Play’n GO slots with the highest maximum win, together with the Coils of Cash slot. We’re talking serious business here.

Hammerfall – Excellent grid slot with medieval theme and blistering win potential

The slot has more in the tank, though. I love the medieval theme, and the animations are spot-on.


Number of paylines: 7×7 grid slot, cluster pays

RTP and variance: 96.2%, Very High variance

Maximum win: 30,000 x the bet or  $€3.0 million

Bonus features: Song features and Hammer High feature

Casino Hipster verdict: HOT! Fantastic grid slot, excellent gameplay with many features and boosters. Brutal win potential!

Besides, the gameplay offers a lot of depth with the numerous features and boosters. Yes, Play’n GO has a high reputation when it comes to grid slots. And now, they have proven again that they are no sissy. On the contrary!

Gameplay and Features

Hammerfall has a 7×7 grid, and it works, like all grid slots, with a cluster pays mechanic and also the avalanche (cascading) mechanicwhere you gain a free re-spin following a win and where winning symbols disappear and make way for new symbols.

The Purple Knight Mask is the best paying symbol, and a 15-symbol cluster yields a 500x win. The other high-paying symbols are a Yellow-coloured Shield, a couple of Hammers and a Green-coloured shield. The five lows are the gems symbols.

The Hammerfall logo’s (letters) are the Wilds. We have the purple ones (with multipliers) and the red ones.

Destruction Features

As Play’n GO does with most of its grid slots, you can benefit from several boosters (Play’n GO calls these the Destruction Features).

Typically you see that low paying symbols are destroyed, sometimes replaced by more lucrative symbols or that symbols transform into matching symbols.

The Song features

You see a Hammer Meter on the left-hand side, which is charged following wins. For example, a winning cluster of six symbols charges the Hammer Meter with six winning symbols. It resets following a loss.

The Twilight Princess Song Feature triggers once the Hammer is fully charged with 25 winning symbols. Here you get a 2×2 Mega wild which is added on the grid.

If you get the 25 winning symbols again,  you trigger the Second to None Song Feature. Now all high-paying symbols transform into matching high-paying symbols.

If you fill the Hammer Meter again, you activate the And yet I Smile Song Feature, where all low-paying symbols are destroyed.

The Hammer High feature

If you manage to charge the Hammer Meter with 50 winning symbols at once, you get to access the more lucrative Hammer High feature. Now you get all three abovementioned Song Features in succession.

As said, if you land 15 or more Purple Knight Masks, you get a 500x win. But there are wilds with multipliers so that wins can be in the thousands.

Hammerfall slot: the payout rate (RTP) is 96.20%

The RTP of Hammerfall is 96.20%, around the average of the RTP’s of all Play’n GO slots.

Perhaps needless to say, but beware that even the most trustworthy online casinos offer this game at less favourable terms and, therefore, a lower RTP.

Hammerfall slot: the variance (volatility) is very high

Hammerfall is a very volatile slot, and perhaps even extremely volatile, given its enormous win potential (max win of 30.000x).

For comparison, the famous Book of Dead slot, which, by many, is perceived as a very volatile slot, has a max win of “only” 5.000x!

I expect that the top wins will easily top 5.000x or even 10.000x!
