Slot machines have come a long way since their humble beginnings in the late 19th century. These games of chance have evolved from simple mechanical devices to complex digital systems that offer immersive sessions. Today millions of people around the globe enjoy spinning the reels, whether in traditional gambling hubs or on their mobile devices.
Birth of the One-Armed Bandit
The story of slot machines begins in 1891. Two men from New York made the first gambling machine. Their names were Sittman and Pitt. Their machine had five drums. It had 50 poker cards on the drums. Players put in a nickel and pulled a lever. They hoped to get a good poker hand.
But the first true slot machine came in 1895. Charles Fey made it in San Francisco. He called it the “Liberty Bell.” It was simpler than the poker machine. It had three reels instead of five drums. It had five symbols: horseshoes, diamonds, spades, hearts and a Liberty Bell. The Liberty Bell symbol gave the biggest win. It also gave the machine its name.
Fey’s machine was special for another reason. It could make automatic payouts. This was a big step forward. Players at Mell Stroy Casino did not need a bartender to give them their winnings anymore.
Key Features of the Liberty Bell
- Three spinning reels
- Five symbols (horseshoes, diamonds, spades, hearts, Liberty Bell)
- Automatic payout system
- Cast iron case
- Single lever operation (the “arm” in “one-armed bandit”)
Fruit Machine Era
In 1902 slot machines were banned in many places. Makers had to find a way around the law. They made new machines that gave out fruit-flavored gum instead of money. The reels showed pictures of fruit. Cherry, lemon, plum and melon symbols appeared. These symbols are still used today.
The BAR symbol also came from this time. It was based on the logo of the Bell-Fruit Gum Company. These machines were called “fruit machines” or “chewing gum dispensers.” But people knew they were really for gambling.
Electric Age Begins
The first big change came in 1964. Bally made the first fully electric slot machine. It was called “Money Honey.” It still had a lever on the side. But all the inside parts were electric, not mechanical. Money Honey could make bigger payouts. It could pay up to 500 coins without help from a person.
Soon after, the side lever was not needed anymore. Buttons replaced levers. This was the end of the “one-armed bandit” nickname. Slots became faster and more fun to play.
Digital Revolution
The 1970s and 1980s brought more changes. Video slots were born. The first one was made in 1976 by Fortune Coin Company. It used a modified 19-inch Sony TV for the display. These new video slots were tested at the Las Vegas Hilton Hotel. After some changes to stop cheating, they became very popular.
In 1996 WMS Industries Inc. made “Reel ’Em In.” This was the first slot with a bonus round on a second screen. When the bonus round started, a new screen would appear. Players could win extra money in this special round. This feature is now in most video slots.
