What is a Slot?

In a massive showroom in the Palais des Congrès in Montreal, Quebec, slot machine makers gather to show off their latest machines. The room is abuzz with beeps and flashing lights, and well-dressed men and women push buttons and levers and watch cherries and sevens spin on liquid crystal displays. It seems like a fun place to be, but it’s really an all-business affair.

While no one has uncovered the Platonic ideal of a slot game, there are certain principles that undergird most games. First, there’s a vague aesthetic uniformity: colors tend toward primary or pastel, franchise tie-ins are a must, and soundtracks typically follow a major key. Second, there’s a tangle of options: modern slots offer upwards of 50 and sometimes 100 different possible winning combinations, which means that even the most advanced players have trouble knowing whether they’ve won or lost.

Despite these odds, many players remain addicted to the game. Schull’s research shows that people play slots for a variety of reasons, but the most common is to “zone out,” or to distract themselves from their daily problems.

In the context of a Web site, a slot is a dynamic placeholder that waits for content (passive slot) or calls out for it (active slot). A slot can contain a Media-image repository item, a Renderer, or a targeter. Slots and renderers work in tandem to deliver content; slots are the dynamic placeholders, while renderers specify how the content is presented.
