In a slot machine, the reels are vertical columns that spin during a game and then stop to rearrange symbols. If the symbols line up with a payline, the player earns credits according to the payout table. The symbols vary depending on the theme of the slot. Some classic examples include fruits, bells, and stylized lucky sevens. Most slots have a particular theme.
Charles Fey patented the first electromechanical slot machine in 1887. He improved on Sittman and Pitt’s invention by allowing cash to be inserted, allowing automatic payouts, and adding three reels. He also replaced the poker symbols with spades, horseshoes, hearts, and liberty bells. Three aligned liberty bells would win the biggest jackpot, which gave the machines their name.
