The first mechanical slot machine was built in 1887 by Charles Fey, and it had three spinning reels and a diamond, heart, spade, or cracked Liberty Bell symbol on each one. Today’s variations of the slot are much more sophisticated and feature multiple paylines, random number generators, video graphics, and branded content.
