main slot online terbaru di rumah The first slot machine, known as the Liberty Bell, was invented by Charles Fey in San Francisco in 1895. This machine had three reels and five symbols: horseshoes, diamonds, spades, hearts, and a Liberty Bell. The simplicity of the game, combined with the potential for monetary rewards, made it an instant hit. Players would insert a nickel and pull a lever to spin the reels. When three Liberty Bell symbols aligned, the machine paid out 50 cents.
