Believe it or not, the payouts on slot machines weren’t always in the form of money, but instead, some of the first ones rewarded people with bubble gum as well as other kinds of merchandise. Since then, they’ve come a very long way to become what they are today. Dating back since 1895 when the great mechanic from San Francisco named Charles Fey built the first three-reel slot machine. Since the very beginnings when the slot machine was first introduced to the public, it has become a favorite casino game to play among millions of people from all over the world.
