    • Wild: The game’s wild symbol is represented by the hammer symbol.
    • Scatter: The scatter icon comes in the form of the cash shields.
    • Mystery Symbols: The silver armor with a lightning strike icon acts as this game’s mystery symbol. Each time the mystery symbols land on the reels, they land as full or partial stacked symbols. Once they land, the mystery symbols transform into the same standard symbol.
    • Mystery Spin: This is a randomly triggered feature. When it triggers, a minimum of three reels transform into full mystery stacks and will reveal the same symbol after the spin.

    • Colossal Respins: Each time players land the wild symbol, the Colossal Respins feature triggers. During the respins, the colossal wild is guaranteed to occupy reels 1 and 2. Landing a wild during the respin will help retrigger another spin. Additional wilds landed help increase the size of the colossal wild up to reel 4. If players keep retriggering respins to reach the fourth respin, a 2x multiplier is awarded. This multiplier will increase by one on each new respin. Colossal symbols landing during this feature including cash shields are counted by the number of positions they occupy.

    • Hold & Win Respins: Six or more cash shields landing on the reels at once help the player trigger the Hold & Win Respins feature. Three respins are awarded when the feature triggers with all triggering symbols turning into sticky icons for the rest of the feature. All other cash shields that land during the feature will also transform into sticky icons. Each time new cash shields or special shields appear on the reels, the respins counter is reset back to three. Once the respins counter reaches zero, the feature comes to an end and all cash values are paid. The special shields that appear during the feature include the following:

    • Red Shield: The shield multiplies all cash values currently in view by a 2x multiplier
    • Green Shield: This shield helps the player collect all cash values by opening up more spaces
    • Purple Shield: The purple shield adds one extra reel to the grid. A maximum of 7 reels may be activated
    • Blue Shield: This is the cash boost shield which boosts all cash values currently in view
    • Yellow Shield: This shield increases the number of respins by three.
    • Thunderstorm Prizes: This slot comes with three thunderstorm prizes. Namely, these are the mini, major, and mega prizes. These prizes are only available during the Hold & Win feature. The thunderstorm prizes are unlocked once three storm shields are collected. When the prizes are unlocked, one prize is awarded at random.
