Start and Grow
In the early 1900s, mechanical slot machines moved out of bars into other spots. These simple machines used reels and springs and could pay out coins, cigars, or drink tokens. They got more popular even as some people tried to stop gambling. Makers got clever with fruit symbols to keep using them.
The Power Shift
The 1960s brought a big change with electric slot machines. These new types had lights, sounds, and worked better with less work needed. Electromechanical systems made a bridge between old-school games and the electronic ones we see now.

- Many ways to win
- Bonus rounds
- Big jackpots
- Better pictures and effects

The Start of the Liberty Bell Slot Machine: A Gambling Step Up
Charles Fey’s Big Idea
In 1895, San Francisco mechanic Charles Fey started something huge in gambling by making the first auto slot machine, the Liberty Bell.
In his small basement, Fey built this three-reel machinist dream, changing betting shops for good.
The machine had five clear symbols: hearts, diamonds, spades, horseshoes, and the big liberty bell, each painted on metal loops.
Smart Mechanics
The Liberty Bell slot machine worked with a clever set-up inside.
You put in a nickel and pulled a lever to make it go. When three bells lined up, it paid out 50 cents on its own – no need for people to do it. This made life much easier in gambling spots.
Growing the Business
Fey had great business skill because he kept full control over his invention. He didn’t sell the idea but put his Liberty Bell machines in San Francisco bars and shared the money. This smart move worked well, and by 1896 he left cars behind to make more slot machines. This choice started a big industry of making and selling slots everywhere.
The Growth of Old Mechanical Slot Machines (1896-1920)
Big Changes in Slot Building
After Fey’s big start with the Liberty Bell, the slot industry grew fast from 1896 to 1920.
Mills Novelty Company became a top name, making a new Liberty Bell in 1907. They added famous fruit symbols and made the machines better.
Slots Move Around
By 1908, mechanical slot machines were not just in bars anymore. They were in bowling alleys, tobacco shops, and barber shops, reaching more people.
The Industry Novelty Company changed the game with a slot machine that gave out gum, using fruit signs for different flavors. This was a clever way to keep selling slots with rules against betting.
Better Tech in Old Machines
From 1911 to 1916, slots saw new tech ideas like:
- The skill stop button (1911)
- Self-paying tech (1913)
- Hold and draw options (1916)
These steps set the stage for modern game types, leading to the tech we use now.
The Start of Electric Slots
The First Electromechanical Slots
In the 1930s gaming world, slots moved from simple mechanical parts to smart electric devices.
Bally Manufacturing Company led the way in 1934, making the first “Bally Baby” – a slot machine that mixed old parts with new electric bits. This set new levels for game quality and features.
Better Tech and Its Effects
The 1940s brought better gaming tech with new payout ideas and multiplier options.
A key moment was in 1963 when Bally launched Money Honey, the first fully electromechanical slot. It could pay out 500 coins all by itself, a big change for casino work.
Adding electric parts to mechanical bits changed how we bet, prepping the way for today’s digital slots.
