What Are Expanding Wild Slots?
Wild symbols are pretty straightforward—they substitute for any symbol to make a winning line, where possible.
Expanding wilds go a step further by taking over the whole reel or even more, making vast swathes of the board wild and leading to some truly insane winning combinations.
Expanding wild slots start off with one symbol that moves across the reel, substituting for all symbols. These symbols are not quite the same as block wild symbols, which don’t expand and aren’t usually able to wild the whole board like expanding wilds can unless the block falls exactly across three lines.
Expanding wilds are often triggered when the wild symbol falls on the third reel or on the lowest win line, although this is not always the case.
