Pragmatic Play
Prepare for a Viking-inspired adventure in Hammerstorm.
Red, green, and purple lightning symbols are collected by the Double, Expand, or Spins chests above the reels. Randomly, any of the three gems can trigger the Respins feature with 5 respins.
During the feature, coin and lightning symbols with values up to 10,000x can hit. On each respin, a 2×2 zone appears on a random position on the grid, collecting any coin or lightning symbols that land within it. After collecting 5, 4, and then 3 lightning symbols, the zone expands to 3×3, 4×4, and 5×5, respectively, as well as awarding 3, 2, and 1 additional respins.
