Slot machines are undeniably the most iconic symbol of any modern casino environment.

However, these incredibly advanced digital games had very humble mechanical beginnings.

The very first true slot machine was invented by Charles Fey in the late 19th century.

It featured three spinning reels and five simple symbols, including horseshoes and a cracked bell.

The Era of Electromechanical Slots

For decades, machines remained purely mechanical, requiring a physical pull of the lever.

The landscape changed forever when Bally introduced the first electrically powered machine.

Modern internet casinos feature an endless variety of highly advanced digital slot games.
