A slot machine is a gambling machine that accepts cash or paper tickets with barcodes as payment and displays a series of reels to generate combinations of symbols. Players activate the machine by pressing a button (either physical or on a touchscreen). The symbols vary depending on the game, but classics include fruits, bells, and stylized lucky sevens. Many slot games have a theme, and bonus features are often aligned with that theme.
Modern electronic slot machines can display the number of credits the player has earned by hitting certain symbols on a payline. Some have more than one payline, and each line can have different symbol odds. This can lead to disputes when the machine malfunctions and appears to have paid out more than it actually did.
