Today, slot machines generate over 70% of all casino revenue worldwide, dominating the floors with massive screens and loud music.
From clunky cast-iron contraptions to highly advanced digital computers, the core appeal of pulling the lever has never changed.
The Liberty Bell: The First True Slot Machine
Before the Liberty Bell, gambling machines required a bartender to manually hand over a prize, like a free beer or a cigar.
To win the ultimate jackpot of fifty cents, a player simply had to line up three Liberty Bell symbols across the single payline.
- When gambling was temporarily banned, the machines were altered to dispense fruit-flavored chewing gum instead of cash
- This era is exactly why we still use ‘fruit symbols’ like cherries and melons on modern slot machines today
- The famous ‘BAR’ symbol originally represented the corporate logo of the Bell-Fruit Gum Company
The Video and Digital Revolution
Instead of physical reels, the Fortune Coin machine used a modified 19-inch Sony television to display digital, computer-generated symbols.
However, the introduction of the Random Number Generator (RNG) microchip proved that the digital games were completely fair and random.
