Hammerstorm Demo Online

Embark on a Viking-inspired journey in Hammerstorm. Collect red, green, and purple lightning symbols from chests above the reels. These can randomly trigger Respins with 5 respins. During this feature, coins and lightning symbols worth up to 10,000x can appear. On each respin, a 2×2 zone appears at a random position on the grid, collecting any coin or lightning symbols that land within it.

As the zone fills with 5, 4, and then 3 lightning symbols, its size expands to 3×3, 4×4, and 5×5, respectively, along with awarding additional respins. Modifiers can also be active during the feature, including Double, which adds a gold version of coin and lightning symbols collected twice; Expand, which increases grid size from 5×5 to 7×7; and Spins, which adds a +1 Spin symbol.

The Respins feature can be triggered by landing the Thor symbol on reel one with at least one lightning symbol elsewhere. When activated, up to three modifiers may be in play, adding gold versions of symbols or expanding the grid. A moving zone then collects prizes that land within it, awarding additional respins as needed.
