A slot is a dynamic placeholder that either waits for content (passive) or actively calls out for it (active). Slots and renderers work together to deliver content. For example, a slot can be filled with content from the Media-image repository and a renderer can specify how this content is displayed on the page.
A slot is a narrow opening, especially one into which something can be fitted. The word is from the Latin slitus, meaning “narrow cut.” The meaning “a position in a series or sequence” was first recorded by 1520s; that of “the space on the (semi-circular) copy desk at a newspaper” is recorded from 1917. It also means a position or job, as in “the slot on the editorial team” or “a position on the football field.” The idiom is often used to refer to a specific machine or game. The first thing to do when playing a slot is check out its pay table. This will give you an overview of the symbols in a slot, alongside how much you can win by landing three, four or five matching symbols on a payline. It will also explain any special symbols such as Wild or Scatter. If a slot has additional features such as Adjacent Pays or Multiway Xtra Wins, these will also be listed in the pay table. A player must be able to understand these symbols in order to play the slot successfully. This can be difficult, as many slot games have a unique look and feel.
