What Is a Slot?


A thin opening or groove in something, such as a door or a piece of furniture. You can put coins or letters through a slot in a wall. Also called a slit, notch, or slitte.

A place on an airplane or in a vehicle that is reserved for a particular person or activity. You may also use this term for a position or assignment, such as the job of chief copy editor: “She has always had her own slot on the Gazette.” A gap between the tips of an aircraft wing that helps to maintain a steady airflow during flight.

a position at an airport, as authorized by an air-traffic control agency: “He has his own slot at Heathrow.”

A slot is a small opening on the surface of a coin, often with a picture of a rabbit or lion, or a diamond-shaped hole in the center. Typically, the slot is painted or plated in color. There are many different types of slot, some used as collectibles and others for play on a casino floor or in a video game.

Despite their bright colors, quirky themes and enticing sounds, slot machines don’t necessarily offer you the best odds of winning. That’s because modern slot machines use random number generators to choose the sequence of symbols that stops on each reel. This means that each spin is independent of the one before it, and that there are no patterns or tricks to beat the machine.
