Charles Fey invented slot machines in 1895. He was a car mechanic and he lived in San Francisco, California. The fist machine ever made was the Liberty Bell. It had 3 reels with hearts, diamonds, spades and a broken Liberty Bell painted around the reels. Three bells in the pay line produced a jackpot, that in those times where 50 cents or 10 nickels.
Nowadays, you can find the first Liberty Bell slot machines at the Liberty Bell Saloon & Restaurant in Reno Nevada.

Vending machines were call slot machines also, but latter it became exclusive for the gambling devices. Charles Fey’s Liberty Bell was a complete success. A few years later, in 1907, a Chicago arcade machines manufacturer, made a series of machines alike Fey’s and they were well known as Operator Bell.
