Slot machines have travelled a far cry from their infancy existence as a mechanized device for current modern video gaming. The first arcade machines, widely recognised as “one-armed bandits”., appeared in the late 19th century. They were completely mechanised units with a side-mounted leverage which triggered the spinning of the reels. Their primitive design and ease of use made them are hugely favoured in pubs and casinos. Over time, slot machines evolved into electromechanical devices that began to utilise electric parts for improve functionality and reliability.
