A slit or other narrow opening, especially one for receiving something, as a coin or a letter.

In computing, a slot is a container that holds dynamic content. A slot can either wait for an action to call it (a passive slot) or be filled by a renderer that adds items to it.

A slot can also refer to a position in a sequence or series, as when you reserve a time slot on the internet to visit a Web site. A slot in a computer can be used to store data or run software applications.

Many gamblers believe that a machine that hasn’t paid off recently is “due” to hit, so they move on to another machine. This belief is based on the fact that the random number generator in a slot machine assigns different probabilities of hitting a specific symbol to each reel. So a machine that has not paid off recently might look like it’s due to, but the probability is still low. There is no logic to this reasoning, and moving on to a new machine might result in a longer losing streak.
