A German immigrant Charles Fey created and developed the very first slot machine in the late 1800s in San Francisco. A metal box, which he called The Liberty Bell, had a window with three metal reels and stood on cast-iron feet.

These machines needed a nickel to play and had ten different symbols, creating a thousand possible combinations. A player won a whopping jackpot of 10 nickels if he lined up three Liberty Bells (compelling a number of winners to happily sing America, the Beautiful).

In the 1940s, back when Bugsy Siegel laid the groundwork for Las Vegas gambling, slot machines were just an afterthought, a small distraction to keep most wives occupied while the husbands played blackjack or craps. Slots were referred to as one-armed bandits due to their poor odds. Lately, a generation later, slot machines have a peek at this web-site turned the tables as a more popular game and have a widespread appeal that drives today's casinos.
