Hammerstorm unleashes a Viking‑forged respin experience built around lightning‑charged symbols, expanding grids, and a roaming collection zone that grows stronger as you gather power. With coin and lightning prizes reaching 10,000×, three powerful modifiers, and a feature that can trigger randomly or through Thor himself, this is a high‑volatility brawler where every respin feels like a strike of the hammer.
Hammerstorm is played on a 5×3, 40‑line layout. Above the reels sit three chests — Double, Expand, and Spins — each linked to red, green, and purple lightning symbols. Collecting these lightning symbols can randomly trigger the Respins feature with 5 respins. During the feature, coin and lightning symbols land with values up to 10,000×, and a roaming collection zone gathers any prizes that land within it. The feature can also be triggered directly by landing Thor on reel 1 alongside at least one lightning symbol anywhere else.
The game channels a rugged Viking atmosphere — storm clouds, runic carvings, and electrified symbols crackling with power. The chests above the reels glow as they collect lightning, and the respin feature erupts with heavy metal energy as the collection zone stomps across the grid. The animations are bold and weighty, giving every expansion, modifier, and prize collection a satisfying impact.
