What Is a Slot?

A narrow depression, notch, groove, or slit, especially one for receiving something, as a coin or a letter. Also called sloth hole. Also used figuratively: A position or place in a group, sequence, or series; an assignment; a job opening. See also time slot (def. 2).

The main goal of slots is to generate winning combinations of symbols on the reels. These combinations trigger pay-table bonus rounds and second screen jackpots. Today, there are many different types of slots. They can be themed after movies, TV shows, and even cities and countries. Each has its own rules and payout values. Some have multiple pay lines, others have Free Spins and other special features.

While most players have dreamed of scoring a jackpot at some point, it’s important to remember that winning big in a slot machine isn’t always easy. It is important to set limits for yourself, and know when it’s time to quit. It’s also a good idea to play in a responsible gaming environment where you can access helpful resources and support.

A slot is a dynamic placeholder that either waits for content (a passive slot) or calls out for it (an active slot). Content is dictated by the scenario using an Add Items to Slot action or a targeter. Slots work in tandem with renderers to deliver the content to the page. Several slot properties are particularly important for offer management. See the Using Slots chapter in the ATG Personalization Programming Guide for more information.
