This invention by Charles Fey laid the foundation for modern slot machines, and many similar machines were produced. Named ‘Liberty Bell', the slot machine featured three spinning reels with various symbols including horseshoe, diamond, spade, heart, and Liberty Bell, and if a player lands three Liberty Bell symbols in a row, they win the highest payout.
