Walking Wilds are a special form of the popular Wild symbols. As is generally known, a wild symbol is a "joker". This means that a wild symbol substitutes for (almost) every other winning symbol, so that sometimes attractive wins can be created. Scatter and other bonus symbols are usually not replaced by a wild symbol. Meanwhile, there are several "variations" of the coveted Wild symbols. These include Sticky Wilds, Stifting Wilds, Expanding Wilds, Cascading Wilds and Walking Wilds.
Translated, "Walking Wild" means something like "wandering wilds". The special thing about these wild symbols is that these symbols move a little bit further on the reel with every spin. This means that a Walking Wild symbol usually results in another free spin. In this subsequent game round, the wild symbol will then change its location and light up again in a different position. This process can be repeated several times until the Walking Wild symbol is no longer visible on the reels.
It becomes especially promising for players when more than one Walking Wild symbol is on the move on the slot reels. Of course, it is no surprise that such Walking Wild symbols are rather the exception due to their attractive winning prospects on the reels.
So far, there are not very many virtual slot machines that come with the exciting Walking Wilds feature. The most popular slot games currently include Jack and the Beanstalk Slot and The Invisible Man Slot in particular.
