Further on, it would be impossible not to mention the personality of an infamous Charles Augustus Fey, who created a slot machine with automatic payouts and actual metal reels. By including only five symbols to his invention, including spades, hearts, diamonds, horseshoes, and, most importantly, liberty bell, the slot machine of Fey has become known as the so-called “Liberty Bell.”

Fey, a great mind, indeed, did not patent his creation, leading to the extreme popularization of slot machines similar to a “Liberty Bell,” which lasted up to 1902, which was a horrific year for the developing industry. Slot machines with their cash prizes were officially banned in the US, leading to the popularization of trendy fruit machines, which awarded players with chewing gums and sweets instead of monetary incentives.

A real revolution took place only in 1963, almost a half-decade later the ban of slot machines, when Bally released their electromechanical slot called “Money Honey.” It revolutionized the industry by incorporation two seemingly opposite things, namely a mechanical lever that had to be pulled and fully electrical wheels.
