Slots with expanding and walking wilds
Two related tricks: an expanding wild swells to cover a whole reel, while a walking wild shifts one position per spin and leaves the grid after a few moves, granting a respin each time. Both raise the odds of a long combination without touching the underlying line maths, which is why studios pair them with low payline counts. The genre classics are Starburst, with its expand-and-respin loop, and Wild Toro, where the bull charges across the entire screen.
How this slice was built
32 games out of the 996 in the catalog. The industry has no shared vocabulary for mechanics: studios describe the same thing in different words, so this list is assembled from a normalised set of spellings found in provider specifications — expanding wilds, expanding wild, walking wilds, walking wild, jumping wilds, transferring wilds. If a game uses the mechanic but the provider never listed it, it will not show up here.
