A slot is a machine that accepts cash or paper tickets with barcodes to register wins. Depending on the type of machine, the player can select a number, or push a lever or button (physical or virtual). This activates the reels to stop at various positions, and awards credits based on the paytable. Symbols vary by machine, but classic symbols include fruits and stylized lucky sevens. Most slot games have a theme, and the symbols and bonus features are aligned with that theme. In some cases, the theme is a fictional character or location. In other cases, it’s a genre of film or television. Many slot games also feature a secondary theme, which is less prominent but still influences the game’s symbols and payouts.
