Respins Feature

The respins feature is the main mechanic in Hammerstorm and can be triggered in two ways:

  1. Randomly: By collecting red, green, or purple Lightning symbols in the chests above the reels during the base game.
  2. Thor Trigger: Landing the Thor symbol on reel one along with at least one Lightning symbol anywhere else on the grid.

When the round starts, you get five respins on a 5×5 grid. A 2×2 collection zone appears and moves to a new random spot after each respin. Any Coin or Lightning symbols that land inside this zone have their values collected.
