What Is a Slot?

A narrow depression, perforation, or aperture, especially one that fits or slides into something larger. (Australian rules football, informal) A position or period within a schedule or sequence; e.g., I’ve booked my haircut for 2 p.m.

Slot is a type of dynamic item that can be used to deliver content in the ATG Service Center. In its simplest form, it’s a placeholder that either waits for content to be added to it (passive slot) or calls out for it to be added to it (active slot).

In addition, slots are mapped to a slot type. This determines the way that the slot is processed and what information it can display.

Traditionally, slot machines have been games of chance. Players insert cash or, in ticket-in, ticket-out machines, paper tickets with barcodes, into a slot that activates the reels. The symbols on each reel spin and stop randomly, and if they match a winning combination according to the machine’s paytable, the player wins credits based on the number of stops on the reels. Manufacturers configure the odds of each symbol appearing by weighting it relative to other symbols. For example, cherries may appear more frequently than stylized lucky sevens. Modern electronic slot machines, however, work on a different principle. Instead of using mechanical gears, they use a central computer to control the outcome of each spin. The computer also uses a random number generator to produce a sequence of numbers that corresponds to symbols on the reels.
