Slot is an arcade game that involves spinning reels with symbols and a pay-line. It can be played with a coin or paper ticket that contains a barcode. The symbols and bonus features vary depending on the game’s theme. Many slot games are themed after popular culture, including movies, TV shows, and rock bands.
