Set on a 5×3 grid with 40 paylines, this release offers a max win of 10,000x your stake. With crisp visuals, animated chests above the reels, and thunder-charged features, Hammerstorm leans heavily into its Viking theme, combining Hold & Win-style respins with lightning-triggered modifiers.

Hammerstorm Slot Bonuses and Features
Thor & Lightning Symbols. Two key symbols dominate the base game:
- Lightning Symbols. Appears in three colours and fill one of three chest meters: Double, Expand, and Spins. They can also randomly carry cash values from 0.5x to 10,000x your bet.
- Thor Symbol. Appears only on reel 1. When Thor lands alongside at least one Lightning symbol, the Respins feature is instantly triggered.
Respins Feature. Once triggered, the grid expands to a 5×5 layout, and classic symbols disappear in favour of Silver and Gold coins and Lightning symbols carrying cash values. The round begins with 5 respins and a 2×2 highlighted collection zone in the center gathers values from symbols it touches. Collecting Lightning symbols fills the vertical meter on the left, progressively expanding the collection area (3×3 to 4×4 to 5×5) and awarding extra respins (+3, +2, +1 respectively). Lightning symbols can be upgraded by unlocking the corresponding chest modifiers:
- Double: Allows Gold coins to appear, each worth twice their displayed value.
- Expand: Enlarges the play area up to 7×7. With each expansion, 3 extra Lightning symbols land.
- Spins: Simply adds one more respin.
The respins round continues until no spins remain.
Bonus Buy (Ante Bets). Players can fast-track their way into bonus round via two Ante Bet options, depending on your region:
- Ante Bet 1 (25x): Guarantees the Thor Scatter symbol lands on reel 1.
- Ante Bet 2 (50x): Ensures at least five Lightning symbols appear, helping you get into Respins.
Conclusion
Hammerstorm slot from Pragmatic Play strikes a balance between simplicity and big rewards. At its heart lies a Hold & Win respins mechanic that builds tension through expanding collection zones and three unique modifiers. The bonus round is quite immersive, especially when Thor appears to trigger the storm, and the visual shifts from day to night helps the game feel more immersive.
However, some players might find the slot a bit boring after a while, with no main free spins bonus, and a heavy dependance on the respins. But for fans of high-stakes pot-style mechanics, decent visuals, and a satisfying jackpot of 10,000x, Hammerstorm is a solid and entertaining experience.
