What is a Slot?

A slot is a dynamic placeholder on the web page that either waits for content (a passive slot) or calls out to a renderer to fill it with content (an active slot). A slots contents are dictated by either a repository item with a Add Items to Slot action or a trigger that uses a targeter.

A slot machine is a casino game that utilizes a random number generator to display symbols on a set of reels. Players insert cash or, in ticket-in, ticket-out machines, a paper ticket with a barcode into the machine to activate the reels and earn credits based on the symbols displayed. Typically, winning combinations of symbols are determined by matching them along a payline. Symbols vary between games, but classic symbols include fruits, bells, and stylized lucky sevens.

The developers of slot games begin the creative process by conducting market research to understand their audience. They also conduct user tests to see how well their product works and if there are any potential bugs that need to be fixed.
