Hammerstorm Review—Editor’s Impressions
The brutality, chaos, and genius of the Vikings have given us numerous top online slots going back many years. In this Hammerstorm slot review, we’ll cover the latest iteration of this nomadic civilisation with a Pragmatic Play slot that combines warrior symbols, respins, and multipliers.
Hammerstorm Slot Overview
A quaint coastal village provides the backdrop for this slot, with the Viking warrior symbols—a Shield, an Axe, a Helmet, Gauntlets, and a Horn—contrasting the peaceful setting. Thor’s hammer, Mjölnir, serves as the Wild, while low-paying symbols consist of card ranks from A to J.
There are 40 paylines in this Pragmatic Play slot, all paying from left to right.
Hammerstorm RTP, Payout, and Volatility
The Hammerstorm RTP varies, with online casinos opting for either 96.50%, 95.50%, or 94.50%. The top end of this range is above average; the middle rate is below average but acceptable. We’d recommend avoiding the lower range where possible.
The max win is 10,000x, and this hits with a frequency of just under one in 1.6 million spins. It sounds like a lot, but as with top payouts in jackpot slots, these caps are designed to pay infrequently. It’s also far from the lowest hit rate we’ve seen.
Pragmatic Play rates the volatility as 5/5, putting it in the “very high” category.
Hammerstorm Mobile
In typical Pragmatic Play style, the mobile version looks just as slick and stylish as the desktop one, with only a few minor tweaks, including a larger spin button and a smaller backdrop. Play Hammerstorm on iOS or Android, with compatibility for most devices, including older phones and tablets.
Hammerstorm Graphics and Gaming Experience
Hammerstorm features a soundtrack reminiscent of a historical RPG—peaceful flute sounds with occasional drum beats to pick up the tempo. The background is static, but the sunny day turns to a charming nighttime scene when you trigger the main feature. It doesn’t have the impact of top Viking-themed 3D online slots, but it works, and we enjoyed our time with the Hammerstorm slot demo.
Hammerstorm Bonus Features
You’ll see three different Lightning symbols on the reels. They correspond to chests above the reels and fly to those chests at the end of a spin, offering a chance to trigger one of three feature modifiers.
We played dozens of spins and collected many Lightning symbols without activating the feature. Still, it only took two spins with the Thor Ante Bet (25x the stake) to unlock the feature, as it just requires a Thor symbol alongside a Lightning symbol.
There’s also an Ante Bet that guarantees five Lightning symbols, but costs 50x the stake. These options are not available in all jurisdictions.
Hammerstorm Free Spins Feature
The main feature is a respin round, but with many spins to collect (we had a total of 25 respins in our first trigger), it functions much like a Hammerstorm Free Spins feature.
The goal is to collect Silver and Gold Coins, each displaying monetary values from 0.5x to 10,000x. Lightning symbols also offer big payouts, and only Coins and Lightning symbols can appear on the 5x5 feature grid.
The respin round plays out a little differently depending on the triggering modifier:
Double: Gold symbols pay their value twice.
Expand: The grid expands from 5x5 to 7x6.
Spins: Additional 1+ Spin icons appear, awarding one more respin.
