In 1899 Charles Fey invented the first three-reel slot machine in San Francisco, and his “Liberty Bell” became a popular attraction in saloons.

Modern slot machines have evolved from their mechanical ancestors and combine new age electronics with old-fashioned nostalgia. Players insert cash or, in “ticket-in, ticket-out” machines, paper tickets with a barcode that activate the reels to rearrange symbols and award credits based on the paytable. Modern slot games may also include features such as free spins, Wild Multipliers (which double winning combinations), and Progressive Multipliers (which increase with each subsequent win).
