Charles Fey, a German immigrant, created the first slot machine. It was developed in San Francisco in the late 1800s. He called it The Liberty Bell and had a metal box with three metal reels supported by cast-iron feet.

The machines required a nickel to play. They had ten symbols, making it possible for you to make a thousand combinations. If a player lined up three Liberty Bells, he could win a huge jackpot of 10 nickels. This compelled a few winners and made them sing “America, the Beautiful”.

Slot machines were a minor distraction in the 1940s when Bugsy Siegel was laying the foundations for Las Vegas gambling. Because of their low odds, slot machines were called one-armed bandits. Today, just a generation later slot machines are a much more popular game than they were a generation ago. They have an appeal that drives today’s casinos.

Slots have evolved into an advanced game that is one of the most popular gambling industries. Slot machines are the most popular feature at casinos, tempting players with an endless variety of colors, types and styles. There are many reasons this appeals, but the most obvious is JACKPOT! Many eternal optimists return to the machine’s trip after trip in search of a pot of gold. Despite all the gadgetry and gizmos, slot machines are remarkably easy to use. You just need to pull the lever in newer machines or press the button. This is all. Perhaps that’s just one of the reasons they are so popular.

Slots make great employees and are a big cash cow for casinos. They bring in nearly two-thirds of the revenue in many casinos. They don’t require workmen’s compensation, wages, insurance benefits or tips. They don’t have to be late, call in sick or leave early. They are easy to use and always available. The computerized operating systems allow players to pump coins in at an erratic pace, resulting in a large profit margin for casinos.
