A slot is an opening or groove into which a piece of hardware, such as a printed circuit board or an expansion card, can be inserted. A computer may have several slots for installing add-on cards that provide specialized capability, such as video acceleration or disk drive control. A slot is also a term used in the gaming industry for an area on a machine where a player can place their bets.

A modern electronic slot machine has a credit meter that displays the amount of money or credits currently in the machine. It also has a display that shows what symbols are in play and how much a player has won, or lost, on a given spin. On mechanical slot machines, this display is typically a seven-segment window, while on video slot machines it is usually a multicolored screen with stylized text that fits the game’s theme.

Feature rounds on slot machines are a popular way to keep players glued to their seats and increase the overall value of a session. These rounds often involve free spins, a mini-game or mystery pick game, and additional bonus prizes. Many of these features are triggered by landing three or more special symbols, known as Scatter or Bonus symbols.

Slots are time periods that can be used to track and support workflow objectives. For example, a team might use slot-based scheduling to organize important deadlines for project milestones. This approach helps teams avoid wasting valuable time and resources due to miscommunication or inefficient processes.
