A slot is an opening, hole, slit, or channel in which something can pass. Slots can be found in doors, windows, and walls. In computers, slots are the places where expansion cards are inserted. A slot is also a position on a page or in an app where an item is displayed. The phrase slot is often used to describe a place in a queue or a schedule. People may book a time slot to get an appointment or exam. People can also return books through the outdoor slot in a library or at an election office.

A good slot receiver can catch passes from anywhere in the field, but he is best at running routes and getting open on shorter passes. He is a key part of the offense, especially on third downs.

The odds of a slot game are calculated differently than those of table games, because there are thousands and millions of possible combinations. A slot machine can have multiple paylines and several symbols, including traditional objects like bells or stylized lucky sevens. Symbols and bonus features vary from game to game, but they are typically aligned with the overall theme of the game.

You can create a custom slot type by creating a regular expression (regex) that matches the value of an identified slot in the utterance. This can be useful if you want your bot to recognize specific words or phrases as a particular slot type.
