How Hammerstorm works

The Respins feature starts with 5 respins. A 2×2 zone appears at a random spot each respin and collects coins and lightning symbols; collecting 5, 4 and then 3 lightning symbols grows it to 3×3, 4×4 and 5×5 and adds 3, 2 and 1 respins. Double, Expand and Spins modifiers can be active, and Thor on reel one with a lightning symbol also triggers it.
