2. History of Slot Machines
The history of slot machines dates back to the late 19th century.
Early Mechanical Slots
The first widely recognized slot machine was created by Charles Fey in 1895, known as the “Liberty Bell.” It featured three spinning reels and simple symbols like horseshoes, bells, and playing cards.

With the rise of the internet, slot machines became available online. This allowed players to access games from anywhere using computers or mobile devices.
