In a slot machine, the pay table tells you how much you can win for landing certain symbols on the payline. It is usually displayed above or below the reels, and you can find it on video slots in a help menu. Some slots also offer free spins, jackpot levels, and bonus games, which are triggered when you get certain symbols.
Charles Fey invented the first slot machine in 1887. His invention allowed automatic payouts and had three reels, making it easier to win.
