The Origins of Slot Machines (Late 1800s)
The First Mechanical Slot Machine
The history of slot machines begins in the late 1800s with the invention of the first mechanical gaming device. Charles Fey, a San Francisco mechanic, created the Liberty Bell machine in 1895.
This machine included:

These symbols are still used in many modern slot designs today.
