Wild Fusion (Hyper Wild) is a feature where individual wild symbols in adjacent positions merge to form a larger, more powerful "Hyper Wild" block with an attached multiplier. This Hyper Wild also moves across the reels and later disintegrates back into individual wilds when it reaches the top or disappears. This is distinct from mega-block wilds (which land pre-formed), symbol transformation wilds (which typically change one symbol into another type), or simple multiplier/moving wilds, as it involves the *fusion* and *disintegration* of multiple symbols into a temporary, enhanced state.
