Slot machines are the most popular gambling method in casinos and constitute about 70 percent of casino revenues. Today, most of them are operated by pressing buttons on a touch screen panel on the front of the machine. Slot machines are also known as one-armed bandits because they were originally operated by pulling a lever on the side of the machine (the arm) to spin the reels. The player wins if the symbols on the reels line up in certain combinations as specified by the paytable. The reels display symbols that spin and stop to reveal one or more symbols that determine the outcome of the game. The player inserts a coin or token into the machine and pulls a lever or presses a button to activate the spinning reels.
